- Rewrites cookbook/permutation.md to cover the new operator toolkit:
initializers, crossovers (OX/PMX/CX/ERX), mutations, a 'what should I
use' picker, and a worked GA-on-TSP example. JSS multiset section
explains why the strict-permutation crossovers don't compose with
operation-string encodings and shows the local POX pattern.
- Adds cookbook/multi-objective-combinatorial.md: bi-objective TSP via
NSGA-II, bi-objective knapsack (binary encoding), 3-objective JSS
via NSGA-III, and a hypervolume-based operator comparison.
- Updates choosing-an-algorithm.md to reference the new operators in
the single- and multi-objective decision tables, plus a noting
NSGA-II/III's genericity over Vec<usize> and Vec<bool> decisions.
- SUMMARY.md and cookbook.md updated to list the new recipe.
