    A Two-Level Search Strategy for Packing Unequal Circles into a Circle Container

    We propose a two-level search strategy to solve a two dimensional circle packing problem. At the first level, a good enough packing algorithm called A1.0 uses a simple heuristic to select the next circle to be pa...

    Towards Effective Elicitation of NIN-AND Tree Causal Models

    To specify a Bayes net (BN), a conditional probability table (CPT), often of an effect conditioned on its n causes, needs assessed for each node. It generally has the complexity exponential on n. Noisy-OR reduces...

    Exploiting Historical Relationships of Clauses and Variables in Local Search for Satisfiability

    Variable properties such as score and age are used to select a variable to flip. The score of a variable x refers to the decrease in the number of unsatisfied clauses if x is flipped. The age of x refers to the n...

    Satisfying versus Falsifying in Local Search for Satisfiability

    During local search, clauses may frequently be satisfied or falsified. Modern SLS algorithms often exploit the falsifying history of clauses to select a variable to flip, together with variable properties such...
