%description
A fast and flexible general-purpose implementation of Particle Swarm
Optimization (PSO) and Differential Evolution (DE) for solving global
minimization problems is provided. It is designed to handle complex
optimization tasks with nonlinear, non-differentiable, and multi-modal
objective functions defined by users. There are five types of PSO
variants: Particle Swarm Optimization (PSO, Eberhart & Kennedy, 1995)
<doi:10.1109/MHS.1995.494215>, Quantum-behaved particle Swarm Optimization
(QPSO, Sun et al., 2004) <doi:10.1109/CEC.2004.1330875>, Locally
convergent rotationally invariant particle swarm optimization (LcRiPSO,
Bonyadi & Michalewicz, 2014) <doi:10.1007/s11721-014-0095-1>, Competitive
Swarm Optimizer (CSO, Cheng & Jin, 2015) <doi:10.1109/TCYB.2014.2322602>
and Double exponential particle swarm optimization (DExPSO, Stehlik et
al., 2024) <doi:10.1016/j.asoc.2024.111913>. For the DE algorithm, six
types in Storn, R. & Price, K. (1997) <doi:10.1023/A:1008202821328> are
included: DE/rand/1, DE/rand/2, DE/best/1, DE/best/2, DE/rand_to-best/1
and DE/rand_to-best/2.
