Ž . In this article we compare two contrasting methods, active set method ASM and genetic algorithms, for learning the weights in aggregation operators, such as weighted mean Ž . Ž . WM , ordered weighted average OWA , and weighted ordered weighted average Ž . WOWA . We give the formal definitions for each of the aggregation operators, explain the two learning methods, give results of processin...

We are developing a system which finds a genetic network from data obtained by multiple gene disruptions and overexpressions. We deal with a genetic network as a weighted graph, where each weight represents the strength of activation from a gene to another gene. In this paper, we explain the overview of our system, and our strategy to visualize the weighted network. We also study the computatio...

background:   objective: in this study we performed linkage analysis on a large x linked rsa pedigree to find a novel susceptibility locus for rsa.   materials and methods: a linkage scan using 11 microsatellites was performed in 27 members of a large pedigree of hereditary x-linked rsa. two point parametric linkage was performed using superlink v 1.6 program. results: evidence of linkage was o...

A novel approach for the efficient weighted association rule mining proposed in this present paper. The proposed approach reducts the transactional dataset (weighted) by utilizing the power of Rough Set theory. Furthermore, proposed approach acquires the benefit for weighted measures (w-support, w-confidence) for obtaining the most profitable weighted frequent itemsets and the Genetic Algorithm...

This article describes a discovery-based introduction to elementary genetic algorithms for students of introductory computer science via a series of programming laboratory exercises. The exercises focus on sorting weighted scores, a problem that is both accessible to the novice programmer and seemingly feasible by means of standard sorting methods. Students soon discover that standard, determin...

Changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. Seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. For genetic studies, it is essential t...

results findings showed that the genotype -607a/a is associated with the susceptibility to chronic hepatitis b. furthermore, allele c at position -137 is suggested to play a protective role against development of chronic hbv infection. conclusions host genetic factors play an important role in determining the outcome of hbv infection. it is suggested that il-18 genotype -607 a/a is associated w...

This paper describes a genetic algorithm approach to the dynamic job shop scheduling problem with jobs arriving continually. Both deterministic and stochastic models of the dynamic problem were investigated. The objective functions examined were weighted flow time, maximum tardiness, weighted tardiness, weighted lateness, weighted number of tardy jobs, and weighted earliness plus weighted tardi...
