Complexity of some inverse shortest path lengths problems
The input to an Inverse Shortest Path Lengths Problem (ISPL) consists of a graph G with arc weights, and a collection of source-sink pairs with prescribed distances that do not ne...

Recognition and dualization of disguised bidual Horn functions
We consider the problem of dualizing a Boolean function f given by CNF, i.e., computing a CNF for its dual fd . While this problem is not solvable in quasi-polynomial total time i...
