Fast Molecular Shape Matching Using Contact Maps
... The overall algorithm is similar to the one described in Goldman et al. (1999). Given two two-dimensional contact maps G1 and G2, we first decompose G1 into two 2-stacks and two 2-staircases. Each 2-staircase is then decomposed into two 1-staircases in linear time. We then compute the maximum overla ...
