In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

The paper considers a project scheduling problem in weighted directed graphs in which arcs represent operations while nodes are identified with starting and finishing endpoints of the operations; arc ...

Les procédés usuels de réduction, et en particulier l'algorithme LLL, deviennent plus performants lorsqu'on les adapte à ces structures, Numerous important lattices (𝔻₄, 𝔼₈, the Coxeter-Todd lattice ...
