大部份的优化问题都是多峰函数或病态函数，为了克服基本粒子群算法的缺陷，我研究了以下四种改进的粒子群算法(Most optimization problems are multi-peak functions or ill-conditioned functions. In order to overcome the defects of basic particle swarm optimization, I studied the following four improved particl

用Java语言写的经典推荐算法-BPR，常用做各大推荐算法的baseline.(The classic recommendation algorithm written in Java language - BPR, is commonly used as the baseline for major recommendation algorithms, it may be helpful for your study.)
