Ga poses implicit parallelism and is suitable for implementation on large scale parallel computers . dividing the whole population into sub - populations and coarse - grained island model of exchanging information among sub - populations are the most direct parallel method Gas具有天然的并行性,非常适合于在大规模并行计算机上实现,把串行gas中的单一群体分成多个子群体,各子群体之间相互交换信息的粗粒度并行是将gas并行化的最直接方式。
