shortest-path
Finding a pair of edge disjoint paths in a graph, such that the lengths of each one of the paths is smaller than a given constant
I know how to find a pair of disjoint paths with the minimum sum of lengths (Surballe\'s algorithm). I also have a formulation of an ILP that solves the following problem, which generalizes my problem[详细]

Say I have a vector polygon with holes. I need to flood fill it by drawing connected segments. Of course, since there are holes, I can\'t fill it using a single continous polyline: I\'ll need to inter[详细]

The path tak开发者_StackOverflow社区en does not have to end back at the predetermined vertex. Basically, the traveling salesman problem except that a vertex can be visited more than one time.[详细]
