Hi all,
To improve code readability and interoperability with non-list-derived individuals, I've added a
sizekwarg totools.selDoubleTournamentthat allows the user to supply a "size" function aside from the defaultlen, analogous to thekeyparameter in built-in sorting functions.I've been using DEAP with individuals lacking a built-in
__len__function. Instead, these individuals have several properties that may be useful proxies for "size," which are calculated by an external library rather than being properties of the objects themselves.
