JSO is an organization dedicated to numerical linear algebra and optimization, containing packages to model, solve, benchmark and analyze results efficiently. We aim, among other things, to provide cutting-edge and original solvers and tools for researchers.
Feel free to visit our website juliasmoothoptimizers.github.io for recent updates on the organization.
Interested in the organization? Have a look at @dpo's presentation of JSO on Youtube 📽️ at the JuliaCon2022.
New contributors are always welcome 👋!
First-time contributors might want to have a look at available issues with the label good first issue.
Please visit Contributing section of the website for guidelines.
One of our simplest packages for new contributors is OptimizationProblems.jl.
🥋: All packages have their own documentation. You can also access the tutorial section of the JSO website
🎬: Follow @abelsiqueira's youtube channel for more tutorials in videos!
Feel free to open a discussion if you can't find answers to your questions.
JuliaSmoothOptimizers contains several packages for modeling and solving linear algebra and optimization problems. The optimization solvers all rely on a unified API to communicate with the models, which is the NLPModels API.
You might also be interested in SolverBenchmark.jl to easily compare your solver via performance profiles or tables available in LaTeX or markdown format!
