+# Elite: Dangerous Long-range router
+
+## Features
+
+- Five different routing algorithms:
+  - **Breadth-first search:**, always finds the shortest route but is quite slow
+  - **Bidirectional BFS:**: should give similar route quality to BFS but take less time (not yet implemented)
+  - **A-Star:** has an adjustable tradeoff between speed and quality
+  - **Greedy search:** always picks the next reachable star that's closest to the destination, very fast but very poor quality routes
+  - **Economic:** computes route with lowest possible fuel consumption (WIP)
+- Nice GUI! (made with PyQt5)
+- Two themes! (Dark and Light)
+- Uses data from [EDSM](https://edsm.net/) for star data
+- Only routes through scoopable systems, no more running out of fuel! (assuming you have a fuel scoop)
+- Take fuel consumption into account and add refueling stops along the route (Not yet implemented)
+- Precomputing of BFS routing graphs for:
+  - near-instant routing from your home system to any destination!
+  - near-instant routing any source back to your-home system (WIP)!
+  - near-instant routing between any pair of systems (Not yet implemented, see TODO)
+- Routing code written in Rust, so it's quite speedy!
+- Export routes as HTML, JSON, CSV and SVG (WIP)
+- Automagically copy next jump destination into system clipboard (works by monitoring the player journal file) (Not yet implemented)
+- (optional) Web interface with job queue for route computations and multi-user support
+
+# Installation
+
+## Prerequisites
+
+- Python:
+  - conda ([Miniconda](https://docs.conda.io/en/latest/miniconda.html)/[Anaconda](https://www.anaconda.com/distribution/))
+  - [nox](https://nox.thea.codes/en/stable/index.html)
+- Inno Setup Compiler
+  - Download from [here](http://www.jrsoftware.org/isdl.php)
+  - or install via [scoop](https://scoop.sh/) `scoop install inno-setup`)
+- Visual Studio 2019
+- nightly rust compiler (`x86_64-pc-windows-msvc`)
+
+## Building an installer
+
+(Assuming `conda` is in your `PATH`)
+
+1. Run `nox -k build`
+2. Grab the installer from `installer/Output/`
+
+## Manual installation
+
+(Assuming `conda` is in your `PATH`)
+
+1. Start a Visual Studio 2019 x64 command prompt
+2. Run the following commands:
+
+```
+conda install pycrypto ujson
+pip install setuptools_rust
+pip install .[all]
+```
+
+then you can run `ed_lrr -h` from your command prompt to get help
+
+# Notes on FSD Fuel consumption and jump range
+
+FSD Fuel consumption ([E:D Wiki](https://elite-dangerous.fandom.com/wiki/Frame_Shift_Drive#Hyperspace_Fuel_Equation)): $$Fuel = 0.001 \cdot l \cdot \left(\frac{dist \cdot \left(m_{fuel} + 
+m_{ship}\right)}{boost \cdot m_{opt}}\right)^{p}$$
+
+Solving for $dist$ gives the jump range (in Ly) for a given amount of fuel (in tons) as: $$dist = \frac{boost \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}{m_{fuel} + m_{ship}}$$
+
+Assuming $f_{max}$ tons of available fuel gives us the maximum jump range for a single jump as: $$dist_{max} = \frac{boost \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot f_{max}}{l}\right)^{\frac{1}{p}}}{f_{max} + m_{ship}}$$
+
+Since the guardian FSD booster increases the maximum jump range by $B_g$ Ly we can calculate a correction factor for the fuel consumption as: $$0.001 \cdot l \cdot \left(\frac{boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}{B_{g} \cdot \left(m_{fuel} + m_{ship}\right) + boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}\right)^{p}$$
+
+Incorporating $e_{fuel}$ into the distance equation yields $$dist = \frac{boost \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot e_{fuel} \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}{m_{fuel} + m_{ship}}$$
+
+Expanding $e_{fuel}$ yields $$dist = \frac{boost \cdot m_{opt} \cdot \left(1.0 \cdot \left(\frac{boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}{B_{g} \cdot \left(m_{fuel} + m_{ship}\right) + boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}\right)^{p} \cdot \min\left(f_{max}, m_{fuel}\right)\right)^{\frac{1}{p}}}{m_{fuel} + m_{ship}}$$
+
+Finally, Expanding $dist_{max}$ yields the full equation as $$dist = \frac{boost \cdot m_{opt} \cdot \left(\frac{1000000.0 \cdot \left(\frac{boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}{B_{g} \cdot \left(m_{fuel} + m_{ship}\right) + boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}\right)^{- p} \cdot \min\left(f_{max}, m_{fuel}\right)}{l^{2}}\right)^{\frac{1}{p}}}{m_{fuel} + m_{ship}}$$
+
+Where:
+- $Fuel$ is the fuel needed to jump (in tons)
+- $l$ is the linear constant of your FSD (depends on the rating)
+- $p$ is the power constant of your FSD (depends on the class)
+- $m_{ship}$ is the mass of your ship (including cargo)
+- $m_{fuel}$ is the amount of fuel in tons currently stored in your tanks
+- $m_{opt}$ is the optimized mass of your FSD (in tons)
+- $f_{max}$ is the maximum amount of fuel your FSD can use per jump
+- $boost$ is the "boost factor" of your FSD (1.0 when jumping normally, 1.5 when supercharged by a white dwarf, 4.0 for a neutron star, etc)
+- $dist$ is the distance you can jump with a given fuel amount
+- $dist_{max}$ is the maximum distance you can jump (when $m_{fuel}=f_{max}$)
+- $B_{g}$ is the amount of Ly added by your Guardian FSD Booster
+- $e_{fuel}$ is the efficiency increase added by the Guardian FSD Booster

+
+$$e_{fuel} = \frac{l \cdot \left(\frac{10.0^{- \frac{3.0}{p}} \cdot \left(B_{g} + dist\right) \cdot \left(m_{fuel} + m_{ship}\right)}{boost \cdot m_{opt}}\right)^{p}}{\min\left(f_{max}, m_{fuel}\right)}$$

+# Python API
+
+First the module needs to be imported
+
+```python
+from _ed_lrr import PyRouter, PyShip
+```
+
+Then we need to instantiate a route plotter
+
+```python
+# callback is passed a dict describing the current search state and progress
+def callback(state):
+    print(state)
+
+r=PyRouter(callback)
+```
+
+Optionally ship loadouts can be loaded from the Elite: Dangerous journal files
+
+```python
+ships = PyShip.from_journal()
+```
+
+To plot a route we need to load a list of star systems with coordinates
+
+```python
+r.load("./stars.csv")
+```
+
+After a list has been loaded we can resolve star systems to their IDs
+
+```python
+systems = [
+    # resolve by coordinates, needs to build an R*-Tree so uses a few GB of RAM
+    (0,0,0),
+    # resolve by name, does fuzzy search, has to scan the whole list of system names
+    "Colonia",
+    # resolve by ID, fairly fast, but the IDs are ed_lrr specific
+    3553323
+]
+systems = r.resolve_systems(*query) # this will return a dict mapping the input key to a dict
+assert sorted(systems.keys())==sorted(query)
+sys_ids = {k: v["id"] for k, v in systems.items()}
+```
+
+Once the system IDs are known we can compute a route
+
+```python
+route = r.route(
+    [sys_ids["Sol"], sys_ids["Colonia"]] # route hops, can be any number of systems (at least 2)
+    48.0, # jump range
+    beam_width=1<<12, # beam width to limit exploration (4096)
+    greedyness=0, # greedyness for A* (0=BFS,0.5 = A*, 1=Greedy)
+    max_dist=500, # maximum deviation from straight line (not yet implemented)
+    num_workers=0 # number of workers to distribute the search accross (0 -> serial mode, >=1 -> spawn worker pool)

+# Galactic Travel in Elite: Dangerous
+
+All ships in Elite: Dangerous (E:D) are equipped with a Frame Shift Drive (FSD) which allows them to jumpst vast distances (multiple light years) from one star system to another.
+
+The maximum range you can traverse in a single jump is limited by the maximum fuel consuption per jump of the specific drive (depends on class and rating) and influenced by the following factors:
+
+- Rating of the FSD
+- Class of the FSD
+- Mass of your ship (Base mass+Cargo mass+Fuel mass)
+- Amount of fuel available in the tank
+
+For details see [the chapter detailing FSD fuel consumption](./fsd_fuel.html)
+
+If the ship is equipped with a Fuel Scoop it can:
+
+- Scoop hydrogen from the corona of a star to refill its fuel tank (only applies to stars of class K, G, B, F, O, A or M)
+- Supercharge its FSD to increase the maximum jump range by a factor of:
+  - 4 if supercharging in the jets of a neutron star
+  - 1.5 if supercharging in the jets of a white dwarf star

+# Notes on FSD Fuel consumption and jump range
+
+FSD Fuel consumption ([Elite: Dangerous Wiki](https://elite-dangerous.fandom.com/wiki/Frame_Shift_Drive#Hyperspace_Fuel_Equation)):
+$$Fuel = 0.001 \cdot l \cdot \left(\frac{dist \cdot \left(m_{fuel} + m_{ship}\right)}{boost \cdot m_{opt}}\right)^{p}$$
+
+Solving for \\(dist\\) gives the jump range (in Ly) for a given amount of fuel (in tons) as:
+$$dist = \frac{boost \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}{m_{fuel} + m_{ship}}$$
+
+Assuming \\(f_{max}\\) tons of available fuel gives us the maximum jump range for a single jump as:
+$$dist_{max} = \frac{boost \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot f_{max}}{l}\right)^{\frac{1}{p}}}{f_{max} + m_{ship}}$$
+
+Since the guardian FSD booster increases the maximum jump range by \\(B_g\\) light years we can calculate a correction factor for the fuel consumption as:
+$$ e_{fuel} = 0.001 \cdot l \cdot \left(\frac{boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}{B_{g} \cdot \left(m_{fuel} + m_{ship}\right) + boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}\right)^{p}$$
+
+Incorporating \\(e_{fuel}\\) into the distance equation yields
+$$dist = \frac{boost \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot e_{fuel} \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}{m_{fuel} + m_{ship}}$$
+
+Expanding \\(e_{fuel}\\) yields
+$$dist = \frac{boost \cdot m_{opt} \cdot \left(1.0 \cdot \left(\frac{boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}{B_{g} \cdot \left(m_{fuel} + m_{ship}\right) + boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}\right)^{p} \cdot \min\left(f_{max}, m_{fuel}\right)\right)^{\frac{1}{p}}}{m_{fuel} + m_{ship}}$$
+
+Finally, Expanding \\(dist_{max}\\) yields the full equation as
+$$dist = \frac{boost \cdot m_{opt} \cdot \left(\frac{1000000.0 \cdot \left(\frac{boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}{B_{g} \cdot \left(m_{fuel} + m_{ship}\right) + boost^{2} \cdot m_{opt} \cdot \left(\frac{1000.0 \cdot \min\left(f_{max}, m_{fuel}\right)}{l}\right)^{\frac{1}{p}}}\right)^{- p} \cdot \min\left(f_{max}, m_{fuel}\right)}{l^{2}}\right)^{\frac{1}{p}}}{m_{fuel} + m_{ship}}$$
+
+Where:
+- \\(Fuel\\) is the fuel needed to jump (in tons)
+- \\(l\\) is the linear constant of your FSD (depends on the rating)
+- \\(p\\) is the power constant of your FSD (depends on the class)
+- \\(m_{ship}\\) is the mass of your ship (including cargo)
+- \\(m_{fuel}\\) is the amount of fuel in tons currently stored in your tanks
+- \\(m_{opt}\\) is the optimized mass of your FSD (in tons)
+- \\(f_{max}\\) is the maximum amount of fuel your FSD can use per jump
+- \\(boost\\) is the "boost factor" of your FSD (1.0 when jumping normally, 1.5 when supercharged by a white dwarf, 4.0 for a neutron star, etc)
+- \\(dist\\) is the distance you can jump with a given fuel amount
+- \\(dist_{max}\\) is the maximum distance you can jump (when \\(m_{fuel}=f_{max}\\))
+- \\(B_{g}\\) is the amount of Ly added by your Guardian FSD Booster
+- \\(e_{fuel}\\) is the efficiency increase added by the Guardian FSD Booster

+# Graph Search algorithms
+
+## Breadth-first search (BFS)
+
+BFS expand node in breadth first order while keeping track of the parent node of each expanded node
+
+## Beam search
+
+Beam search is similar to BFS but limits the number of expanded nodes based on a heuristic
+
+## Greedy search
+
+Greedy search is essentially Beam search with a beam width of 1
+
+## Dijkstra
+
+Dijkstra's algorithm finds the shortest path across a graph based on some edge weight
+
+## A*
+
+A* is similar to Dijkstra but uses a heuristic to speed up the search
+
+## Beam-Stack search (BSS)
+
+Beam-Stack search is a variation of beam search which keeps a separate priority queue for each layer of the graph to allow backtracking and expand previously unexpanded nodes
