Study of the NP-completeness of the compact table problem
The problem of compact tables is to maximise the overlap when building a word that is to include permutations of every given words (all the words being the same length). This probl...

The three column Bandpass problem is solvable in linear time
The general Bandpass problem is NP-hard and was claimed NP-hard when the number of columns is three. Previously we designed a polynomial time row-stacking algorithm for the three ...

The k-in-a-path Problem for Claw-free Graphs
Testing whether there is an induced path in a graph spanning k given vertices is already NP-complete in general graphs when k = 3. We show how to solve this problem in polynomial t...
