Control when the iterated local search loop should terminate. Each function
returns a callable object (closure) that the solver invokes every iteration,
receiving the cost of the current best solution and returning TRUE to stop.
Usage
max_runtime(seconds)
max_iterations(max_iters)
no_improvement(n)
first_feasible()
Arguments
- seconds
Maximum run time, in seconds.
- max_iters
Maximum number of iterations.
- n
Number of consecutive iterations without improvement before stopping.
Value
An object of class vrpr_stop: a function
function(best_cost, feasible) returning TRUE/FALSE.
Details
These are the R equivalent of PyVRP's pyvrp.stop module.
