Sergio Nesmachnow,Luis Hernández Callejonodes. We combine this algorithm with a maximum matching algorithm to obtain a . approximation algorithm for all values of .. We also describe how the mathematical programming formulation we give has several advantages over previous approaches which attempted at finding a subgraph with minimum spectral radius given an edge removal budget.

We also show that it is inapproximable to within a factor of .. For certain relaxations of the max-degree constraints, we are able to show constant-factor approximation algorithms for the problem.

In contrast, our implementation relies on a familiar shuffling operation called a random cut, and hence, it can be conducted completely publicly so as to avoid any active attack.

Directed Path-Width of Sequence Digraphs time ., where . denotes the maximum sequence length. This leads to an XP-algorithm w.r.t. . for the directed path-width problem. As most known parameterized algorithms for directed path-width consider the standard parameter, our algorithm improves significantly the known results for a high amount of digraphs of large directed path-width.
