A New Algorithm for MAX-2-SAT, . . is the number of 2-clauses, and . is a polynomial. In addition, our algorithm and the proof are much simpler than the previous ones. The key ideas are to use the symmetric flow algorithm of Yannakakis and to count only 2-clauses (and not 1-clauses).

Circuits versus Trees in Algebraic Complexity,ructure ., it is important to find out whether NP. problems can be solved by polynomial depth computation trees, and if so whether these trees can be efficiently simulated by circuits. Point location, a problem of computational geometry, comes into play in the study of these questions for several st

On the Many Faces of Block Codes, of reducing decoder complexity. Necessary and sufficient conditions for subtrellis overlaying are next derived from the representation of the block code as a group, partitioned into a subgroup and its cosets. Finally a view of the code as a graph permits a combination of two shortest path algorithm

A New Algorithm for MAX-2-SAT, related problems. In particular, for MAX-2-SAT Niedermeier and Rossmanith recently presented an algorithm with worstcase upper bound .(. ·2.), and the bound .(. ·2.) is implicit from the paper by Bansal and Raman (. is the number of clauses). In this paper we improve this bound to .(.)2. ./4, where

Linear Cellular Automata with Multiple State Variables,ective (surjective) if and only if the determinant of its transition matrix is an injective (surjective, respectively) single variable automaton. We prove that in the one-dimensional case every injective automaton can be factored into a sequence of elementary automata, defined by elementary transiti
