Added an example how to call the algorithm
Added option to have bias in the same matrix as weight or as its own vector Changed data parameter name to training_data
turned off plotting for debugging population_evonn now can handle 2d matrices
changed new_CV variable to new_cv according to PEP8
Fixed function names in evonn_problem
Set bias to self.bias value (default=1) Updated delete method in population_evonn to use boolean masks. Keep and delete methods can now be combined
Removed debug examples
Moved these functions out of Population class
The function takes a parameter a list of indices and "delete" or "keep", and either deletes the indices from the population or keeps them and deletes all others.
fixed the Recombination functions to use individuals instead of indices started working on PPGA algorithm
preys and predators are now tracked in a dict within Lattice
optimized predator and prey placement functions added static methods to check for lattice boundaries and neighbours
fixed bug with offspring placing with wrong indices
ignore bias on mutation predator turn now does not end after killing if moves left fixed bugs with offspring placement and indexing
affected by crossover and mutation. PPGA seems to be working as intended now.
fixed the mutation function so that zero weights will not be chosen for mutation
added some comments added reference pictures of the models for docs
added sin, cos, tan and neg functions to biogp added headers to ZDT1 example file fixed EA behavior if no parameters are passed biogp now takes the variables from the data to terminal set by default
removed some old unused parameters
adjusted some default parameters improved documentation
adjusted default parameters
included example test results updated sphinx docs
