WebDec 18, 2024 · Developer of BlackBoxOptim.jl (BBO) here (so slightly biased). Depends on what you mean with GA, BBO has Differential Evolution (DE) which is an Evolutionary Algorithm, like GA. BBO is geared towards optimizing Float64-based vectors though so if you need to optimize Int’s it is not the most natural choice, but see: WebThus, the main focus is on unconstrained optimization. The provided solvers, under certain conditions, will converge to a local minimum. In the case where a global minimum is desired we supply some methods such as (bounded) simulated annealing and particle swarm. For a dedicated package for global optimization techniques, see e.g. BlackBoxOptim ...
