Is your feature request related to a problem?
Yes.
Describe the solution you'd like
I did two separate projects. In the first Lua implementation of the UI and the implementation of the genetic algorithm itself in Rust.
https://github.com/Tiikara/path_of_building_genetic_genetic_lualib - genetic library on rust for lua
https://github.com/Tiikara/pathofbuildinggenetic - PoB with genetic
Describe alternatives you've considered
No response
Additional context
Currently implemented:
- Genetic algorithm
- Multithreaded calculation
- UI interface for setting the values the genetic algorithm will aim for
- Saving the genetic algorithm settings in Build xml
- Displaying the best results in the UI during the optimization process
- Use of conventional nodes
- Using ascendence nodes
- Using mastery nodes
Current issues:
- Slow performance due to long shortest path search (the algorithm takes 20 minutes on my Intel Core i9 12900k and uses 8 gigabytes of memory)
- Memory leak on optimization restart
What needs to be done before merge:
- My fork uses the 64bit architecture and luajit2.1 from https://github.com/openresty/luajit2. Can we already recompile the project to 64bit? :)
The 64bit architecture is necessary because of threads' memory usage. The luajit2.0 used in the project now cannot allocate more than 2 Gbytes of memory, that's why I chose https://github.com/openresty/luajit2 without this limitation.
Project dependencies (runtime_x64) https://github.com/Tiikara/pathofbuildinggenetic compiled with Visual Studio 2019
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start with the linked pathofbuildinggenetic fork and its runtime_x64 dependencies, then compare the Lua UI and Rust genetic library with the main project's LuaJIT 2.0 setup. Reproduce the optimization workflow and investigate the reported 20-minute runtime, high memory use, and restart leak. Done requires a defined merge plan for 64-bit support and agreement on the remaining performance and memory issues.
