Innovation Numbers for Genes #169

Open FaydSpeare opened 5 years ago

FaydSpeare commented 5 years ago

I can't seem to find where innovation numbers for genes are cross-checked with other structural mutations that could have occurred in the generation. It seems like this wouldn't be a problem very often, though theoretically it could happen, riight?

FaydSpeare commented 5 years ago

It could be an interesting addition to specify how many generations after the first instance of a specific structural mutation that a duplicate structural mutation in later generations would still be considered the same (and thus given the same innovation number) . One could also keep a global list of innovation numbers and cross-check any new structural mutations with those that have occurred previously throughout all generations.

Regarding identical mutations within the same generation, it seems someone else has recently complained about this and written themselves a fix (although they have not submitted a pull request). #228
