}Expand description
A ReinsertionOp defines a function that combines the offspring with the
current population to create the population for the next generation.
At the end the new population must be of the same size as the original
population.
The ReinsertionOp may decide which individuals in the offspring will
make it into the new population. It is not required that all individuals
of the offspring are reinserted into the new population.
The only hard requirement is that the new population is of same size as the original population. If the offspring contains less individuals than the size of the original population or not all individuals are moved to the new population then some individuals from the original population are taken over into the new population. If the size of the offspring is bigger than the size of the original population, then not all individuals from the offspring are inserted into the new population.
Required methods
Combines the given offspring with the current population to create the population of the next generation.
The offspring parameter is passed as mutable borrow. It can be
mutated to avoid cloning. The genetic::Genotypes that make it up into
the new population should be moved instead of cloned. After this
function finishes the offspring vector should hold only those
genetic::Genotypes that have not been included in the resulting
population. If by the end of this function all genetic::Genotypes in
offspring have been moved to the resulting population the offspring
vector should be left empty.
