A Good Route Is Not Always a Good Starting Route
TL;DR for operators A dispatch system preparing routes for thousands of destinations has limited time to produce a workable plan. Improving the optimization algorithm is one option; improving the routes supplied to that algorithm is another. The second approach may deliver substantial gains without replacing the existing solver. Zhao and colleagues introduce Just Initialize (JI), a training-free method that constructs starting solutions according to how well they can be improved by subsequent optimization.1 It groups geographically related destinations, searches for promising arrangements of those groups, and reconstructs feasible routes for local refinement. ...
