Classification Association Rule Mining (CARM) systems operate by applying an Association Rule Mining (ARM) method to obtain classification rules from a training set of previously-classified data. The rules thus generated will be influenced by the choice of ARM parameters employed by the algorithm (typically support and confidence threshold values). In this paper we examine the effect that this ...

We present a hill-climbing algorithm to solve planning problems with temporal uncertainty. First an optimistic plan that is valid when all actions complete quickly is found. Then temporal reasoning techniques are used to determine when the plan may fail. At time points that cause an unsafe situation, contingency branches are inserted. We describe our planner PHOCUS-HC, give preliminary results,...

Abstract This chapter presents a novel research collaboration between architects and computer scientists to investigate and develop mobile, context-sensitive serious games for sports and health (so-called exergames). Specifically, it describes a new approach that aims to design exergames which interact with the player’s built, topographic, and social environment in a meaningful way and presents...

INTRODUCTION Arthrodesis of the ankle is an established operation. The lack of normal ankle movement after ankle arthrodesis reduced the ability of the patients to walk smoothly on the arthrodesis foot. It would have a more profound effect in negotiating stairs, because large ranges of dorsiflexion and plantarflexion are required to accomplish this activity. Although gait characteristics have b...

Regaining walking ability is one of the most prominent goals in the rehabilitation program following lower-limb amputation. Walking ability in this context relates to a natural, symmetric, sustainable gait. The ability to monitor walking ability and evaluate gait patterns during the fitting and rehabilitation process is fundamental to achieving these goals. Walking function can be assessed qual...

This paper examines the performance of hill-climbing algorithms on standard test problems for combinatorial auctions (CAs). On single-unit CAs, deterministic hill-climbers are found to perform well, and their performance can be improved signiicantly by randomizing them and restarting them several times, or by using them collectively. For some problems this good performance is shown to be no bet...

We address the basic problem of coordinating the actions of multiple robots that are working toward a common goal. This kind of problem is NP-hard, because in order to coordinate a system of n robots, it is in principle necessary to generate and evaluate a number of actions or plans that is exponential in n (assuming P 6= NP ). However, we suggest that many instances of coordination problems, d...

This paper outlines a general approach to the iterative incremental improvement of the cryptographic properties of arbitrary Boolean functions. These methods, which are known as hill climbing, offer a fast way to obtain Boolean functions that have properties superior to those of randomly generated functions. They provide a means to improve the attainable compromise between conflicting cryptogra...

in this paper presents a maximum power point tracking (mppt) technique based on the hill climbing search (hcs) method and fuzzy logic system for wind turbines (wts) including of permanent magnet synchronous generator (pmsg) as generator. in the conventional hcs method the step size is constant, therefor both steady-state response and dynamic response of method cannot provide at the same time an...
