Another (likely better) option, instead of simplifying while parsing, would be during mutations (like it is done in f1): when mutations add/modify/remove a modifier node, they could "clean" the tree by simplifying modifiers on the same subpath just as GenoOperators::simplifiedModifiers() does. This way, simplifying would be only performed when we actually modify a part of a genotype, not each time we interpret it, and there would be no hidden mechanism: all visible genes would have an expected effect on the phenotype.19 // TODO F4_SIMPLIFY_MODIFIERS in f4_general.cpp: currently it works while parsing (which is a bit "cheating": we get a phenotype that is a processed version of the genotype, thus some changes in modifiers in the genotype have no effect on its phenotype). This is especially noticeable with color modifiers, where simplification only accepts MAX_NUMBER_SAME_TYPE_COLOR. Another (likely better) option, instead of simplifying while parsing, would be during mutations (like it is done in f1): when mutations add/modify/remove a modifier node, they could "clean" the tree by simplifying modifiers on the same subpath just as GenoOperators::simplifiedModifiers() does. This way, simplifying would be only performed when we actually modify a part of a genotype, not each time we interpret it, and there would be no hidden mechanism: all visible genes would have an expected effect on the phenotype. In other words, if a genotype happened to have more modifiers of the same type than allowed by GenoOperators::simplifiedModifiers(), they would all be effective (like in f1) and not silently ignored when interpreting that genotype. For example in /*4*/GGGgGX> due to simplifying modifiers (removing the oldest), only the last G remains effective when MAX_NUMBER_SAME_TYPE_COLOR=1, and it is impossible to adjust colors precisely even by manually editing the genotype - like it is in f1, even though the same simplifying function is used, just in a different moment. 20 20 // TODO improve the way modifiers are handled in the f4->f1 approximate converter (used extremely rarely just for illustration) 21 21 … … 32 32 33 33 34 const char *Geno_f4::all_modifiers = F14_MODIFIERS ","; //comma in f4 is handled the same way (simple node, F4_ADD_SIMP) as modifiers.
