To Do List
- tanimoto coefficient percent change - might be inaccurate due to tan coef behavior
- Rotatable bond changes (???)
- Limit number of aromatic rings.
- -xover (guided based on score) - Good v Good ; Bad v Good ; Bad v Bad THIS
- Nonexhaustive xover (pick subset of xover based on probability)
- Nonexhaustive xover for each pair of parents - have a set number of bonds for xover rather than trying all of them.
- Crossover on multiple points simultaneously (2-3 crossovers on a given pair to make 3+ children rather than 2+).
- Adaptive maintenance of ensemble based on convergence (extinction, delta max, etc.).
- Stop convergence.
- Mutations-
- Adaptive mutation rate - change rate of mutation based on some internal criteria.
- Pick location of mutation based on some internal criteria.
- Pick mutation type based on ensemble behavior.
- If molecules are too large, boost deletion (useful for elitism).
- If molecules are too small, boost additive mutations.
- If molecules are too similar, boost replacements and substitutions.
- mutation type selection based on probability vs ensemble
- Complete x # y mutation so far so less prevalent etc
- Note: 3 layer substitutions probably aren't going to work.
- 2-layer replacements.
- fitness-
- turn on and off niching adaptive/extinction
- reduce boost of fragments and all poor mols with niching
- pareto/mulitobjective ga
- selection-
- Adaptively keep differing #'s of parents and children based on some internal criteria (similarity?)
- extinction-
- which molecules are best-
- best first pruning - now uses descriptor score even if niching ned to delta to fitness/niching when used
- geometric diversity using Hingarian and Tan pruning
- Determine whether the dummy vdw file is necessary for all DN (including GA) or just DN.
- Choose crossover pairs based on measure of similarity (boost crossovers between dissimilar molecules).
Known Bugs
- Molecules Processed bug (dock.cpp)
- verbose mol stats (amber typer)
- molecule being renamed when going into repl even tho it's the same molecule
