Compute Multi-Objective Costs for a Population

Usage

compute_objectives(instance, chromosomes, num_obj, lookup = NULL)

Arguments

instance: Edge-list data.frame (only used when lookup = NULL).
chromosomes: Numeric matrix [pop_size x (n - 2)].
num_obj: Integer.
lookup: Optional list returned by build_weight_lookup.

Value

Numeric matrix [pop_size x (n - 2 + num_obj)].

Examples

inst <- generate_instance(10, 2, seed = 1)
lk   <- build_weight_lookup(inst, 10, 2)
pop  <- generate_prufer_population(10, 5)
compute_objectives(inst, pop, 2, lk)
