Combinatorial abilities and heuristic behavior in online search environments

a framework for identifying and prioritizing factors affecting customers’ online shopping behavior in iran

the purpose of this study is identifying effective factors which make customers shop online in iran and investigating the importance of discovered factors in online customers’ decision. in the identifying phase, to discover the factors affecting online shopping behavior of customers in iran, the derived reference model summarizing antecedents of online shopping proposed by change et al. was us...

Choosing Combinatorial Social Choice by Heuristic Search

This paper studies the problem of computing aggregation rules in combinatorial domains, where the set of possible alternatives is a Cartesian product of (finite) domain values for each of a given set of variables, and these variables are usually not preferentially independent. We propose a very general heuristic framework SC* for computing different aggregation rules, including rules for cardin...

Real-time Heuristic Search for Combinatorial Optimization and Constraint Satisfaction

We summarize a new approach to real-time heuristic tree search for problems with a fixed goal depth, such as combinatorial optimization and constraint satisfaction problems. Best-leaf-first search (BLFS) is a general and complete algorithm that visits leaves in an order that efficiently approximates increasing predicted cost. It can adapt its search order on-line to the current problem. Empiric...

Heuristic Search of Optimal Reduction Schedule in Heterogeneous Cluster Environments

Network of workstation (NOW) is a coste ective alternative to massively parallel supercomputers. As commercially available o -theshelf processors become cheaper and faster, it is now possible to build a PC or workstation cluster that provides high computing power within a limited budget. However, a cluster may consist of di erent types of processors and this heterogeneity within a cluster compl...
