  • evotorch

    EvoTorch is an advanced evolutionary computation library built directly on top of PyTorch, created at NNAISENSE.

    Project mention: NNAISENSE Open-Sources ‘EvoTorch’: An Evolutionary Algorithm Library for the Machine Learning Community | reddit.com/r/artificial | 2022-08-14

    An Advanced Evolutionary library or algorithm has been a dream of scientists and AI/ML enthusiasts since the concept was introduced. This vision has come true thanks to the scientists at NNAISENSE, a Switzerland-based AI Enterprise. They created an open-source platform called EvoTorch. When operated in combination with Machine Learning, it can solve complex operational problems in a fraction of time, with lower costs, and at a larger scale. Evolutionary algorithms act as a step toward solving cascading problems that occur when the problem’s size and complexity increase. Evolutionary algorithms make the situations easier to handle the complexity without adding to the cost, they are also much easier to connect through GPUs and CPUs parallelly to ease up the calculation time and the complexity associated with it, that the only limit to your computational power becomes your budget. The evolutionary algorithms are built in the open framework EvoTorch.

  • python-mip

    Python-MIP: collection of Python tools for the modeling and solution of Mixed-Integer Linear programs

    Project mention: Ask HN: Do you use an optimization solver? Which one? Why? Do you like it? | news.ycombinator.com | 2022-04-20

    I've been using CBC via python-mip (https://github.com/coin-or/python-mip). It's great because it's got a super clean interface (milp variables/expressions/constraints), the code is quite accessible, and it's low overhead which makes it good for solving many very small problems.

    Community sentiment seems to be beginning to shift toward favouring the HiGHS solver (https://github.com/ERGO-Code/HiGHS) over CBC. Something I'm keeping a close eye on.

    nextmv seems to pitch itself as a generic solving ("decision automation") platform or something (unclear). But it seems that the only fleshed out product offering is for vehicle routing, based on the docs. Are there plans to offer, for instance, a solver binary that can be used to solve generic problems?

    Also all the github repos under https://github.com/nextmv-io are private, so links from docs are 404.

  • zoofs

    zoofs is a python library for performing feature selection using a variety of nature-inspired wrapper algorithms. The algorithms range from swarm-intelligence to physics-based to Evolutionary. It's easy to use , flexible and powerful tool to reduce your feature size.

    Project mention: [D] Feature engineering automation? | reddit.com/r/MachineLearning | 2022-04-27

    and as u described considering you will end up with a lot of features. https://github.com/jaswinder9051998/zoofs for feature selection. Zoofs is a wrapper based feature selection, so you'll be able select feature-based purely on performance if u have a healthy test set or if u perform cross-validation

  • ML-Optimizers-JAX

    Toy implementations of some popular ML optimizers using Python/JAX

  • fliscopt

    Algorithms for flight scheduling optimization.

    Project mention: Highlights from Neuromatch 4.0 Conference | dev.to | 2022-01-13

    This poster is interesting for anyone who finds concepts of attention mechanisms, Genetic algorithms interesting. In this poster the authors present an interesting idea as to how, switching mechanisms are responsible for improvements in biological organisms as well as in simulated beings. They take this idea to an extreme by implementing “switching” within an algorithm (Inter algorithmic switching) to between two diff algorithms (Intra algorithmic switching).

  • yaglm

    I made this small package for genetic algorithms in python. And I would like to improve it, do you have any suggestions on how I can go about improving it? PyGenetic

  • ExpensiveOptimBenchmark

    Benchmarking Surrogate-based Optimisation Algorithms on Expensive Black-box Functions

    Project mention: 29 Python real world optimization tutorials | reddit.com/r/optimization | 2022-07-14

    For the problems with continous decision variables it is not trivial to come up with faster approaches on a modern many-core CPU. But even with discrete input (scheduling and planning) new continous optimizers can compete. The trick is to utilize parallel optimization runs and numba to perform around 1E6 fitness evaluations each second. Advantage is that it is much easier to create a fitness function than for instance to implement incremental score calculation in Optaplanner. And it is more flexible if you have to handle non-standard problems. For very expensive optimizations (like https://github.com/AlgTUDelft/ExpensiveOptimBenchmark) parallelization of fitness evaluation is more important than to use surrogate models.
