Analysis of Heuristic Synergies
نویسنده
چکیده
“Heuristic synergy” refers to improvements in search performance when the decisions made by two or more heuristics are combined. This paper considers combinations based on products and quotients, and a less familiar form of combination based on weighted sums of ratings from a set of base heuristics, some of which result in definite improvements in performance. Then, using recent results from a factor analytic study of heuristic performance, which had demonstrated two main effects of heuristics involving either buildup of contention or look-ahead-induced failure, it is shown that heuristic combinations are effective when they are able to balance these two actions. In addition to elucidating the basis for heuristic synergy (or lack thereof), this work suggests that the task of understanding heuristic search depends on the analysis of these two basic actions.

Investigation of Muscle Synergies Using Four Different Methods of Synergy Extraction While Running on a Treadmill in Beginner Runners
Introduction: The study of muscle synergy is a new way to evaluate the functioning of the human body's control system. Different mathematical methods are used to extract muscle synergies from electromyographic data, and this factor can cause different outputs in muscle synergies. Therefore, the aim of this study was to investigate muscle synergies using four different synergy extraction methods...
متن کاملNeuroplasticity and neuromotor synergies in context of rehabilitation after stroke: a systematic review
Background: Alterations of neuroplasticity and cortical excitability are important pathophysiological factors in stroke. Modulation of the neuroplasticity has been proposed as an underlying mechanism of recovery in different neurological disorders. But it is not still clear how the CNS faces the complexity of muscle control. Neuroplastic processes may be used for the functional improvement of s...

متن کاملOptimization of Large Transport Networks Using the Ant Colony Heuristic
Long-term transportation planning in larger regions encompasses more than the evaluation of individual infrastructure projects; it must also assess synergies and interference among sets of projects. The objective is the maximizing of the overall benefit within specific budget restrictions by finding the most favourable bundle of projects, i.e. solving the network design problem. For large numbe...
متن کاملMirror Neurons and (Inter)subjectivity: Typological Evidence from East Asian Languages
Language is primarily constituted by action and interaction based on sensorimotor information. This paper demonstrates the nature of subjectivity and intersubjectivity through the neural mechanism and typological evidence of sentence-final particles from East Asian languages and extends to the discussion of the relationship between them. I propose that intersubjecivity is a kind of embedded or ...
