Lock-free parallel dynamic programming
We show a method for parallelizing top down dynamic programs in a straightforward way by a careful choice of a lock-free shared hash table implementation and randomization of the ...

Optimal Randomized Algorithms for Local Sorting and Set-Maxima
We present randomized algorithms for two sorting problems. In the local sorting problem, a graph is given in which each vertex is assigned an element of a total order, and the task...

Short XORs for Model Counting: From Theory to Practice
Abstract. A promising approach for model counting was recently introduced, which in theory requires the use of large random xor or parity constraints to obtain near-exact counts of...

An Algebra for Cyclic Ordering of 2D Orientations
Wedefine an algebra of ternary relations for cyclic ordering of 2Dorientations. Thealgebra (1) is a refinement of the CYCORDtheory; (2) contains 24 atomic relations, hence 224 gen...
