An Upper Bound for B2[2] Sequences
Abstract. We introduce a new counting method to deal with B2[2] sequences, getting a new upper bound for the size of these sequences, F(N, 2)

Non Uniform Selection of Solutions for Upper Bounding the 3-SAT Threshold
We give a new insight into the upper bounding of the 3-SAT threshold by the first moment method. The best criteria developed so far to select the solutions to be counted discrimina...

Multiply-Recursive Upper Bounds with Higman's Lemma
We develop a new analysis for the length of controlled bad sequences in well-quasi-orderings based on Higman’s Lemma. This leads to tight multiply-recursive upper bounds that re...

Improved Upper Bound for the Redundancy of Fix-Free Codes
A variable-length code is a fix-free code if no codeword is a prefix or a suffix of any other codeword. In a fix-free code any finite sequence of codewords can be decoded in both d...
