CircuitTSAT: A Solver for Large Instances of the Disjunctive Temporal Problem
In this paper, we report on a new solver for large instances of the Disjunctive Temporal Problem (DTP). Our solver is based primarily on the idea of employing "compact" ...

Criticality Metrics for Distributed Plan and Schedule Management
We address the problem of coordinating the plans and schedules for a team of agents in an uncertain and dynamic environment. Bounded rationality, bounded communication, subjectivi...

A New Hybrid Genetic Algorithm for the Job Shop Scheduling Problem with Setup Times
In this paper we face the Job Shop Scheduling Problem with Sequence Dependent Setup Times by means of a genetic algorithm hybridized with local search. We have built on a previous...

What Makes Planners Predictable?
In recent work we showed that models constructed from planner performance data over a large suite of benchmark problems are surprisingly accurate; 91-99% accuracy for success and ...

The Compression Power of Symbolic Pattern Databases
The heuristics used for planning and search often take the pattern databases generated from abstracted versions of the given state space. Pattern databases are typically stored p ...

Scheduling Meetings at Trade Events with Complex Preferences
We present a complex scheduling problem where we want to plan meetings between customers and exhibitors at a trade event. One cause of the complexity of the problem is the general...

Exact Dynamic Programming for Decentralized POMDPs with Lossless Policy Compression
High dimensionality of belief space in DEC-POMDPs is one of the major causes that makes the optimal joint policy computation intractable. The belief state for a given agent is a p...

Efficient ADD Operations for Point-Based Algorithms
During the past few years, point-based POMDP solvers have gradually scaled up to handle medium sized domains through better selection of the set of points and efficient backup met...

Structural Patterns Heuristics via Fork Decomposition
We consider a generalization of the PDB homomorphism abstractions to what is called "structural patterns". The bais in abstracting the problem in hand into provably trac...

Useless Actions Are Useful
Planning as heuristic search is a powerful approach to solving domain independent planning problems. In recent years, various successful heuristics and planners like FF, LPG, FAST...
