method .ctor #

#ctor(PopulationCollection(Of `0), Variant(Of ParallelComputeFitness(Of `0), Boolean))

如果parallel参数不是空的，则会启用这个参数的并行计算

Parameters

Name	Type	Description
`parallel`	PopulationCollection(Of `0)	-

method SortPopulationByFitness #

SortPopulationByFitness(FitnessPool(Of `0))

这里是ODEs参数估计的限速步骤

Parameters

Name	Type	Description
`comparator`	FitnessPool(Of `0)	-

method Add #

Add(`0)

Add chromosome

Parameters

Name	Type	Description
`chromosome`	`0	-

method Trim #

Trim(Int32)

shortening population till specific number

property parallel #

parallel

是否使用并行模式在排序之前来计算出fitness

property Size #

Size

The number of chromosome elements in current population. (请注意,这个属性的值是随着IPopulation.Add()方法的调用而变化的, 如果只需要获取得到种群的固定大小,可以使用IPopulation.capacitySize 属性)

property Random #

Random(Random)

Gets random chromosome

Item(Int32)

Gets chromosome by index

Parameters

Name	Type	Description
`index%`	`Int32`	-
