The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

constraint propagation significantly reduces the number of state expansions, causing our approach to solve more instances than a DP solver for Single Machine Scheduling and RCPSP, and showing similar improvements for tightly constrained TSPTW instances

C2weakest assumption

The overhead of calling a general-purpose CP solver inside the DP loop remains acceptable relative to the pruning gains for the tested problem classes and instance sizes.

C3one line summary

Integrating general-purpose constraint propagation into domain-independent dynamic programming reduces state expansions and solves more instances on scheduling and TSP problems.
