Finite SAGBI bases for polynomial invariants of conjugates of alternating groups
It is well-known, that the ring C[X1, . . . , Xn]An of polynomial invariants of the alternating group An has no finite SAGBI basis with respect to the lexicographical order for any...

A logarithmic-quadratic proximal point scalarization method for multiobjective programming
We present a proximal point method to solve multiobjective problems based on the scalarization for maps. We build a family of a convex scalar strict representation of a convex map...

Lossless Data Compression via Substring Enumeration
We present a technique that compresses a string w by enumerating all the substrings of w. The substrings are enumerated from the shortest to the longest and in lexicographic order...

On the generation of bicliques of a graph
This work describes a study on the generation of bicliques of a graph. We show that it is NP-complete to test whether a subset of the vertices of a graph is part of a biclique. We ...
