Abstract: The Pathwidth Theorem states that if a class of graphs has unbounded pathwidth, then it contains all trees as graph minors. We prove a similar result for dense graphs: if a class of graphs ...

One way to determine if a linear program has an optimal solution is to convert it to its standard form. The standard form of a LP problem is: maximize z = c'x subject to Ax = b x >= 0 where x is the ...
