The blob code is competitive with edge-sets in genetic algorithms for the minimum routing cost spanning tree problem
Among the many codings of spanning trees for evolutionary search are those based on bijections between Pr¨ufer strings—strings of n−2 vertex labels—and spanning trees on th...

Arbitrary convex and concave rectilinear block packing using sequence-pair
The sequence-pair was proposed in 1994 as a representation of the packing of rectangles of general structure. Since then, there have been e orts to expand its applicability over s...

Simple Traversal of a Subdivision Without Extra Storage
In this paper we show how to traverse a subdivision and to report all cells, edges and vertices, without making use of mark bits in the structure or a stack. We do this by perform...
