Framsticks

updated for Framsticks 5.0

Cosmetic

Randomly swap parents in crossover to avoid any imbalances or biases in crossover implementations (in case parent order in the implementation of operators would matter - while we assume it should not)

Fixed the reported fraction of parent1 and parent2 genes in the child, when the second child is chosen (the fractions were previously swapped in this case, i.e, they did not match the order of parent names)

Offset of fields within an object: replaced subtraction of pointers/addresses with the official offsetof()

Added realloc() implementation that behaves like free() when size==0 - consistently on all platforms, in contrast to standard realloc()

Color mutations in f1 and f4, and a new syntax for "allowed modifiers" (opposite to previous "excluded modifiers") with optional probabilities for each modifier

Cosmetic

Introduced FITNESS_VALUE_INFEASIBLE_SOLUTION and modified selection and statistics so that infeasible solutions are explicitly excluded (previously they were not excluded from statistics calculation, and eliminating/discriminating them during selection only relied on their relatively poor fitness value)

Introduced GENOTYPE_INVALID_OFFSPRING_SUBSTITUTE_ORIGINAL (True by default) for developers who do not specifically detect and handle returned invalid genotypes after mutate() and crossOver()

Print genotypes that may have caused problems when being evaluated - useful when reproducing the problem

Added the ability to select a dissimilarity measure for crowding distance (for NSGA2 and NSLC) independently from the main dissimilarity measure

• compatibility update for modern blender versions (2.80 or later)
• optional, enabled by default: use a single shared mesh instance for all sticks
• the stick cylinder is now capped

Introduced symbolic names for dissimilarity estimation methods

Cosmetic

Added archive to the NSLC algorithm

Default parameter values for mutations: f1 and f4 "excluded modifiers" became "allowed modifiers", and f0 and f0s separate r,g,b mutation probabilities became a single color mutation probability
