Data members
| Name | Type | Utility |
|---|---|---|
m_inds |
vector<unique_ptr<Individual>> |
Member individuals of the current population |
m_iter |
size_t |
The current number of iterations |
m_id |
int |
The index number in the multi-population |
m_best |
vector<unique_ptr<Individual>> |
Best individuals found so far |
m_worst |
vector<unique_ptr<Individual>> |
Worst individuals found so far |
In multi-modal or multi-objective optimization, there may be more than one best and worst individuals.
