This paper uses a penalty guided strategy based on an artificial bee colony algorithm (PGBC) to solve the redundancy allocation problem (RAP) in reliability series–parallel systems. The penalty strategy was designed to eliminate the equalities in constraints and formulate new objective operators which guarantee feasibility within a reasonable execution time. The PGBC is used to deal with two ki...
Resumo Objetiva-se discutir equidade e acesso em saúde mental por meio da análise distribuição das equipes atenção primária (Agentes comunitários de Saúde; Equipes Família; Núcleo Ampliado Saúde Família) cobertura Rede Atenção Psicossocial (RAPS) três estados nordestinos (Ceará, Piauí Rio Grande do Norte) nas suas respectivas regiões saúde. Trata-se um estudo descritivo, apoiado quantitativa ex...
This paper investigates the development of an effective heuristic to solve the set covering problem (SCP) by applying the meta-heuristic Meta-RaPS (Meta-heuristic for Randomized Priority Search). In Meta-RaPS, a feasible solution is generated by introducing random factors into a construction method. Then the feasible solutions can be improved by an improvement heuristic. In addition to applying...
BACKGROUND Smoking is the most important individual risk factor for many cancer sites but its association with breast and prostate cancer is not entirely clear. Rate advancement periods (RAPs) may enhance communication of smoking related risk to the general population. Thus, we estimated RAPs for the association of smoking exposure (smoking status, time since smoking cessation, smoking intensit...
Host resistance has become a viable approach to eliminating aflatoxin contamination of maize since the discovery of several maize lines with natural resistance. However, to derive commercial benefit from this resistance and develop lines that can aid growers, markers need to be identified to facilitate the transfer of resistance into commercially useful genetic backgrounds without transfer of u...
Background: The NSF specifies that mental health service providers should have a locally agreed proforma for assessing risk. Risk assessment proformas (RAPs) currently in use vary considerably in both structure and content. This study describes some similarities and differences. Method: We requested a copy of each provider trust’s RAP. These were assessed across a range of structural characteri...
The construction of good starting solutions for multi-start local search heuristics is an important, yet not well-studied problem. In these heuristics, randomization methods are usually applied to explore new promising areas and memory mechanisms are incorporated with the main purpose of reinforcing good solutions. Under the template of a typical multi-start metaheuristic, Meta-RaPS (Meta-heuri...
