Module list_solver 

List variable solver for routing and scheduling problems.

This module provides ListSpec for problems with list variables (e.g., vehicle routes, shift schedules). The solver configuration (construction type, move selectors, acceptor, forager, termination) is driven by solver.toml.

Logging levels:

• INFO: Solver start/end, phase summaries, problem scale
• DEBUG: Individual steps with timing and scores
• TRACE: Move evaluation details
