Apr 27, 2012 · The width measures are either applied in terms of the primal graph of the formula. (variables are vertices, two variables are adjacent if they ...
The results lie in the fact that they allow us to exploit algorithmically a hidden structure in formulas that is not accessible by any one of the two ...
There are various approaches to exploiting "hidden structure" in instances ofhard combinatorial problems to allow faster algorithms than for ...
