This is a function to just return a matrix that defines the sitewise dependencies for an NK fitness landscape. If K == 0 or, this is not an NK simulation, it return NULL
set_const_NK_interactionsMat(func_simModel = getOption("shape_simModel"),
func_genomeLength = getOption("shape_genomeLength"),
func_numInteractions = getOption("shape_const_numInteractions"))
This is the fitness landscape model being simulated
This is the number of sites in the genome being simulated
An integer value defining the number of sites that interact with each other site
Either NULL, or a matrix with K + 1 columns, detailing the sites interacting with a focal site - identified by the row number and the cell values of the columns.
