Modeling and solving the non-smooth arc routing problem with realistic soft constraints
作者:
Highlights:
• A realistic version of the arc routing problem with soft constraints is analyzed.
• Soft constraints might cause non-smooth objective functions challenging to optimize.
• A novel mathematical model for the non-smooth arc routing problem is introduced.
• A heuristic combining biased randomization with iterated local search is proposed.
• We improve previous works, a linearized version of the problem is solved with CPLEX.
