Long Nonbinary Codes Exceeding the Gilbert - Varshamov Bound for any Fixed Distance
Let ( ) denote the maximum size of a -ary code of length and distance . We study the minimum asymptotic redundancy ( ) = log ( ) as grows while and are fixed. For any and 1, long a...

Two-Layer Planarization Parameterized by Feedback Edge Set
Abstract. Given an undirected graph G and an integer k ≥ 0, the NPhard 2-Layer Planarization problem asks whether G can be transformed into a forest of caterpillar trees by remov...

Extremal graphs for the identifying code problem
An identifying code of a graph G is a dominating set C such that every vertex x of G is distinguished from all other vertices by the set of vertices in C that are at distance at m...

Stable Minimum Storage Merging by Symmetric Comparisons
We introduce a new stable minimum storage algorithm for merging that needs O(m log( n m + 1)) element comparisons, where m and n are the sizes of the input sequences with m ≤ n. ...

An Improved Algorithm for Minimum-Area Retiming
The concept of improving the timing behavior of a circuit by relocating flip-flops is called retiming and was first presented by Leiserson and Saxe. The ASTRA algorithm propose...
