Lexicase survival

[rgupta90]

This has issues and doesn't run. Creating request for analysis in this separate branch.

Gives error 'bool' is not a type identifier in

cdef void _epsilon_lexicase "epsilon_lexicase"(Map[ArrayXXd] & F, int n, int d, int num_selections, Map[ArrayXi] & locs, bool lex_size, Map[ArrayXi] &sizes)

[lacava]

this might help

done. removed message array declaration

looks good. just one line i would remove.

In few/lib/epsilon_lexicase.h https://github.com/lacava/few/pull/23#discussion_r130663852:

• // individual locations
• vector ind_locs_temp(sizes[random_index]);
• ind_locs = ind_locs_temp;
• //ind_locs.reserve(sizes[random_index]);
• }
• else{
• // individual locations
• vector ind_locs_temp(n);
• ind_locs = ind_locs_temp;
• //ind_locs.reserve(n);
• }*/
• vector ind_locs;
• if(lex_size){ +vector ind_locs(n); +if(lex_size){ char message[200];

get rid of this

I guess you were referring to resizing in else statement by just declaring above, instead of defining size. I tried that and seems to work fine with accuracy always improving now with lex_size as compared to, without it. (ran both 3-4 times) So, seems to work good.

ind_locs.resize(n); should work.

i finally got this to compile on my system. there was a dangling build of the shared object in ~/anaconda3/lib/python3.5/site-packages/ that was giving an argument mismatch. it seems to work well now. I also added a test for the lex_size flag to test_selection.py.

Sounds great!
