  Shortest paths in time-dependent FIFO networks
Dehne F., Omran M., Sack J. Algorithmica 62(1-2): 416-435, 2012.  Type: Article

The natural goal of routing algorithms is to identify the least costly paths between sources and destinations. When costs are related to distances, as they frequently are, the least costly paths become the shortest paths. This paper pr...

  Generating triangulations at random
Epstein P., Sack J. ACM Transactions on Modeling and Computer Simulation 4(3): 267-278, 1994.  Type: Article

Two polynomial-time algorithms are presented. The first counts the triangulations of a simple plane polygon having no holes or self-intersections. The other generates such triangulations with uniform probability distribution (every tri...

  Computational Geometry: Theory and Applications (v.1 n.1)
Sack J. Urrutia J. (ed)  Computational Geometry: Theory and Applications 11:1991.  Type: Journal

In a 1989 survey talk, I predicted that two new journals devoted to computational geometry would appear within a decade. My prediction was realized in under two years, with the publication of the International Journal of Computation...

  Algorithms for minimum length partitions of polygons
Lingas A., Levcopoulos C., Sack J. BIT 27(4): 474-479, 1987.  Type: Article

The authors present a compact description of an algorithm of time complexity O(n3m2) for finding a minimum length diagonal partition of a simple polygon into faces under two conditions: either...
