Climate change is one of the most serious challenges confronting agriculture, particularly, in rural Nigeria. This study examined the perception, adaptation strategies and challenges of climate change among rural households in Kogi State, Nigeria. A two stage sampling techniques was used in the study. The first stage involves the purposive selection of six (6) rural farming communities, followe...

We revisit Gaussian Adaptation (GaA), a black-box optimizer for discrete and continuous problems that has been developed in the late 1960’s. This largely neglected search heuristic shares several interesting features with the wellknown Covariance Matrix Adaptation Evolution Strategy (CMA-ES) and with Simulated Annealing (SA). GaA samples single candidate solutions from a multivariate normal dis...

Step length adaptation is central to evolutionary algorithms in real-valued search spaces. This paper contrasts several step length adaptation algorithms for evolution strategies on a family of ridge functions. The algorithms considered are cumulative step length adaptation, a variant of mutative self-adaptation, two-point adaptation, and hierarchically organized strategies. In all cases, analy...

This paper studies the effects of psychological, individual, product strategy, and situational factors on the impulse purchase behavior of customers in all Refah stores located in Tehran. The paper uses Betty and Ferrell Model to set forward and to test 4 hypothesis. All four hypothesis were confirmed. The results indicated that the selected factors had impact on the impulse behavior of the con...

this paper presents an overview of new approaches in rapid product development in production networks from design points of view. the manufacturing industries are changing their focus to global sourcing as a means to improve performance and enhance competitiveness. some partnerships created with this strategy improve product development through collaborative design. with the advent of e-commerc...

In order to catch up with reality, all the macro-decisions related to long-term mining production planning must be made simultaneously and under uncertain conditions of determinant parameters. By taking advantage of the chance-constrained programming, this paper presents a stochastic model to create an optimal strategy for producing bimetallic deposit open-pit mines under certain and uncertain ...
