verify_that_generated_solution_really_is_a_solution: Verify that solution does cover all species

In langfob/bdpg: Package For Building and Testing Biodiversity Problem Generators

Verify that solution does cover all species

Description

Theoretically, this should not be necessary, but checking it here to make sure that the implementation is working correctly. Correct solutions will have every species attaining a representation fraction of their target of at least 1 (where 1 means exactly meeting their target).

Usage

verify_that_generated_solution_really_is_a_solution(
  bpm,
  dependent_node_IDs,
  num_spp,
  num_PUs,
  PU_costs
)

Arguments

bpm	bipartite matrix; integer matrix with one row for each species and one column for each planning unit. Each matrix entry specifies whether that species occupies that planning unit; 1 indicates the species does occupy the planning unit and 0 indicates it does not. Same as occ_matrix.
dependent_node_IDs	integer vector of IDs of planning units contained in a constructed correct solution to a Xu problem
num_spp	integer number of species in the problem
num_PUs	integer number of planning units
PU_costs	numeric vector of planning unit costs

Value

Returns TRUE if given solution does cover all species targets; quits otherwise
