Programmers can work transparently with data from these various sources, relying on DB2 II's global query optimizer to select an efficient data access strategy for such work.
程序员可以透明地使用来自这些不同数据源的数据，并通过DB2II全局查询优化器来选择一个有效的数据访问策略。
The proposed algorithm is almost as simple for implement as particle swarm optimizer, but can improve the abilities of seeking the global excellent result and evolution speed.
该算法基本保持了粒子群优化算法简单容易实现的特点，但改善了粒子群优化算法摆脱局部极值点的能力，提高了算法的收敛速度和精度。
