The choices for mining of decentralized data are numerous, and we have developed techniques to enumerate and optimize decentralized frequent itemset counting. In this paper, we introduce our heuristic approach to improve the performance of such techniques developed in ways similar to query processing in database systems. We also describe empirical results that validate our heuristic techniques.

Memory-based heuristic techniques have been used to effectively reduce search times in implicit graphs. Recently, these techniques have been applied to improving search times in explicit graphs. This paper presents a new memory-based, additive heuristic that can be used on a type of explicit graph: the four-connected gridworld. The heuristic reduces the number of expanded nodes by up to five ti...

Heuristic search is a general problem solving technique. While most evaluations of heuristic search focus on the speed of search, there are relatively few techniques for predicting when search will end. This paper provides a study of progress estimating techniques for optimal, suboptimal, and bounded suboptimal heuristic search algorithms. We examine two previously proposed techniques, search v...

Heat transfer takes place in every aspect of our daily life. Many situations, such as energy conversion plants, heating devices, and cooling systems, focus on heat transfer. One the subjects is boundary layer laminar flow problem. Well-known exploratory algorithms are used to solve for a flat plate this study. The genetic algorithm (GA), particle swarm optimization (PSO), simulated annealing (S...

This paper introduces a new formulation for GPS networks which is an important technique in Surveying. The objective is to find an effective receiver schedule at least cost using heuristic techniques within the field of Operational Research. To evaluate the solution, a comparison with known optimal solution is made. Large networks (with unknown optimal schedules) were solved using Simulated Ann...

With the advancement of internet technologies and multimedia applications, spectrum scarcity problem is becoming more acute. Thus, spectral-efficient schemes with minimal interference for IoT networks are required. Device-to-device communication (D2D) technology has potential to solve issue in future wireless networks. Additionally, throughput considered a non-convex NP-hard problem, heuristic ...
