In this paper, we present programs in Picat for solving three planning puzzles, including 15-puzzle, Klotski, and the Rubik's cube. All these programs use the planner module of Picat. For a planning problem, we only need to specify the conditions on the final states and the set of actions, and call the planner on an initial state to find a plan or a best plan. The planner module uses tabling. It tables...
Picat is a new and interesting programming language, combing many different programming paradigms: logic programming, imperative programming, functional programming, constraint programming, and tabling. This paper is a personal discussion of some of Picats features with several code examples.
Cell formation consists in organizing a plant as a set of cells, each of them containing machines that process similar types or families of parts. The idea is to minimize the part flow among cells in order to reduce costs and increase productivity. The literature presents different approaches devoted to solve this problem, which are mainly based on mathematical programming and on evolutionary computing...
