标准的粒子群算法程序代码，相对简洁，求解二维的带约束优化问题(Newton method for solving linear constrained problems)

带有不等式/等式约束的加速粒子群算法（apso），主要通过罚函数来进行约束，速度较快，可处理带约束问题(Accelerated particle swarm optimization (APSO) with inequality / equality constraints, which is mainly constrained by penalty function, is fast and can deal with constrained problems)
