+Built-in operator packs for standard problems.
+
+Each pack provides problem-aware custom operators that can significantly
+improve solution quality for specific problem types. Users load them like:
+
+    from cugenopt.operator_packs import tsp_ops
+    result = cugenopt.solve_custom(..., custom_operators=tsp_ops)
+
+Or with built-in solvers:
+
+    result = cugenopt.solve_tsp(dist, custom_operators=tsp_ops)
