…n mu_lambda in Evolution.jl. This resulted in substantial speedups, expecially for larger, more redundant, chromosomes. function print_chromosome in Chromosome.jl is broken and not fixed, and the code is not cleaned up.
…re parallel to Chromosome which can store the "active" and "cache" fields of nodes. Modified Chromosome to add this parallel data structure. Added NodeCache.jl and ChromosomeCache.jl to the files listed in CGP.jl. However, at this point, even "using CGP" is not working.
The cache is defined in ChromosomeCache.jl and NodeCache.jl, and is a parallel data structure that contains the "active" and "cache" filds in each node. A chromosome can be executed without using the "active" and "cache" fields using execute_chromosome() and with using these fields by using execute_chromosome_cache(). Appropriate modifications to Mutate.jl and to function print_chromosome() in Chromosome.jl have NOT been made.
… to Chromosome.jl and Node.jl
which stores the cache and active fields for each node of a Chromosome.
This allows execution with and without caching. For single-ouput goals, without caching seems to be
considerably fast.
The other changed files adapt to these changes in the data structures.
…romosome.jl and test/Evolution.jl.
…osomeCache to Union(Nothing,ChromosomeCache). When there is no cache, this field will be "nothing". Revised comments and fixed a bug in examples/EvolveGoals.jl
…in examples/EvolveGoals.jl.
