On Grid Graph Reachability and Puzzle Games

1 code implementation2 Oct 2023 Miquel Bofill, Cristina Borralleras, Joan Espasa, Mateu Villaret

Many puzzle video games, like Sokoban, involve moving some agent in a maze.

Towards a Model of Puzznic

no code implementations2 Oct 2023 Joan Espasa, Ian P. Gent, Ian Miguel, Peter Nightingale, András Z. Salamon, Mateu Villaret

We report on progress in modelling and solving Puzznic, a video game requiring the player to plan sequences of moves to clear a grid by matching blocks.

A Good Snowman is Hard to Plan

1 code implementation2 Oct 2023 Miquel Bofill, Cristina Borralleras, Joan Espasa, Gerard Martín, Gustavo Patow, Mateu Villaret

In this work we face a challenging puzzle video game: A Good Snowman is Hard to Build.

Challenges in Modelling and Solving Plotting with PDDL

no code implementations2 Oct 2023 Joan Espasa, Ian Miguel, Peter Nightingale, András Z. Salamon, Mateu Villaret

We study a planning problem based on Plotting, a tile-matching puzzle video game published by Taito in 1989.

A Preliminary Case Study of Planning With Complex Transitions: Plotting

no code implementations27 Oct 2021 Jordi Coll, Joan Espasa, Ian Miguel, Mateu Villaret

Plotting is an example of a planning problem: given a model of the environment, a planning problem asks us to find a sequence of actions that can lead from an initial state of the environment to a given goal state while respecting some constraints.

SAT Encodings for Pseudo-Boolean Constraints Together With At-Most-One Constraints

no code implementations15 Oct 2021 Miquel Bofill, Jordi Coll, Peter Nightingale, Josep Suy, Felix Ulrich-Oltean, Mateu Villaret

When solving a combinatorial problem using propositional satisfiability (SAT), the encoding of the problem is of vital importance.

Nominal Unification and Matching of Higher Order Expressions with Recursive Let

no code implementations16 Feb 2021 Manfred Schmidt-Schauß, Temur Kutsia, Jordi Levy, Mateu Villaret, Yunus Kutz

We also provide a nominal unification algorithm for higher-order expressions with recursive let and atom-variables, where we show that it also runs in nondeterministic polynomial time.
