In this paper, we propose a search technique for nurse scheduling, which deals with it as a multi-objective problem. For each nurse, we first randomly generate a set of legal shift patterns which satisfy all shift-related hard constraints. We then employ an adaptive heuristic to quickly find a solution with the least number of violations on the coverage-related hard constraint, by assigning one...

Large animals have a disproportionate capacity to transport nutrients along gradients and against water flow directions, making them more available to ecosystems and ultimately saving them from disappearing in sea floor sediments. Megafauna extinctions have reduced this capacity dramatically, while humans and their livestock aren’t stepping in to restore this important ecosystem service.

1 LIP6, Université Pierre et Marie Curie, 4 Place Jussieu, 75252 Paris Cedex 05, France. [email protected] Abstract. Knowledge about forced moves enables to select a small number of moves from the set of possible moves. It is very important in complex domains where search trees have a large branching factor. Knowing forced moves drastically cuts the search trees. We propose a language an...

UK higher education institutes are lobbying to get the commission to accept the idea of credits based on learning outcomes rather than length of study. But within the UK, Scottish and Welsh universities are already implementing credit systems compatible with the European Commission's system. The Bologna process objectives enthuse many people. George Winckler, president of the European Universit...
