In this paper, hybrid technique with differential evolution (DE) method as a global search technique and binary successive approximation (BSA) based evolutionary search method as a local search technique is proposed. Evolutionary search is used for the exploration and pattern search method for exploitation. To initiate with good population, the opposition based learning strategy is applied. Mig...

We present a platform that integrates a number of process model search techniques and provides a uniform interface for query formulation and search result presentation, as well as a framework to evaluate a particular search technique. The platform provides researchers with a common infrastructure to embed their search technique in form of a dedicated search engine. The demo explains the feature...

This paper presents a common algorithmic framework encompassing the two main methods for using an abstract solution to guide search. It identifies certain key issues in the design of techniques for using abstraction to guide search. New approaches to these issues give rise to new search techniques. Tw o of these are described in detail and compared experimentally with a standard search techniqu...

W model portions of the search tree via so-called search constraints. We focus on a particular kind of search constraint, the k-discrepancy constraint appearing in discrepancy-based search. The property that a node has an associated discrepancy k can be modeled (and enforced) through a linear constraint. Our key result is the exploitation of the k-discrepancy constraint to improve the bound giv...

nowadays, scientific c findings in the field of regeneration of nervous system have revealed the possibility of stem cell based therapies for damaged brain tissue related disorders like stroke. furthermore, to achieve desirable outcomes from cellular therapies, one needs to monitor the migration, engraftment, viability, and also functional fate of transplanted stem cells. magnetic resonance ima...

In this paper, an adaptive step size auto focus search algorithm and a reduced zoom tracking algorithm are proposed. Many different auto focus search algorithms exist, such as global search, binary search, Fibonacci search, and so on. Global search can ensure the global peak is found correctly, but the search time is too long. The search time of binary or Fibonacci search is shortened, but the ...

This paper considers the scheduling problem of parallel batch processing machines with non-identical job size and processing time. In this paper, a new mathematical model with ready time and batch size constraints is presented to formulate the problem mathematically, in which simultaneous reduction of the makespan and earliness-tardiness is the objective function. In recent years, the nature-in...

cost optimization of the reinforced concrete cantilever soil retaining wall of a given height satisfying some structural and geotechnical design constraints is performed utilizing harmony search and improved harmony search algorithms. the objective function considered is the cost of the structure, and design is based on aci 318-05. this function is minimized subjected to design constraints. a n...
