Domain-Independent Dynamic Programming

2 code implementations25 Jan 2024 Ryo Kuroiwa, J. Christopher Beck

We experimentally compare our DIDP solvers with commercial MIP and CP solvers (solving MIP and CP models, respectively) on common benchmark instances of eleven combinatorial optimization problem classes.

PRP Rebooted: Advancing the State of the Art in FOND Planning

no code implementations18 Dec 2023 Christian Muise, Sheila A. McIlraith, J. Christopher Beck

Fully Observable Non-Deterministic (FOND) planning is a variant of classical symbolic planning in which actions are nondeterministic, with an action's outcome known only upon execution.

Domain-Independent Dynamic Programming: Generic State Space Search for Combinatorial Optimization

1 code implementation26 Nov 2022 Ryo Kuroiwa, J. Christopher Beck

For combinatorial optimization problems, model-based approaches such as mixed-integer programming (MIP) and constraint programming (CP) aim to decouple modeling and solving a problem: the 'holy grail' of declarative problem solving.

Combinatorial Optimization

(Unconstrained) Beam Search is Sensitive to Large Search Discrepancies

no code implementations27 Sep 2018 Eldan Cohen, J. Christopher Beck

We find that increasing the beam width leads to sequences that are disproportionately based on early and highly non-greedy decisions.

Comparing and Integrating Constraint Programming and Temporal Planning for Quantum Circuit Compilation

no code implementations19 Mar 2018 Kyle E. C. Booth, Minh Do, J. Christopher Beck, Eleanor Rieffel, Davide Venturelli, Jeremy Frank

Our hybrid methods use solutions found by temporal planning to warm start CP, leveraging the ability of the former to find satisficing solutions to problems with a high degree of task optionality, an area that CP typically struggles with.

Scheduling a Dynamic Aircraft Repair Shop with Limited Repair Resources

no code implementations4 Feb 2014 Maliheh Aramon Bajestani, J. Christopher Beck

To solve the problem, we view the dynamic repair shop as successive static repair scheduling sub-problems over shorter time periods.
