The p-median problem is one of the discrete optimization problem in location theory which aims to satisfy total demand with minimum cost. A high-level algorithmic approach can be specialized to solve optimization problem. In recent years, meta-heuristic methods have been applied to support the solution of Combinatorial Optimization Problems (COP). Collision Bodies Optimization algorithm (CBO) a...

O presente artigo tem por objetivo investigar as virtudes e fragilidades da Instituição Fiscal Independente (IFI) do Brasil, tendo base a literatura internacional, boas práticas recomendadas organizações internacionais, exemplo Organização para Cooperação Desenvolvimento Econômico (OCDE), bem como experiência Congressional Budget Office (CBO), exitosa IFI dos Estados Unidos América. Ao final, c...

We document an increase in the likelihood of women working a good job (those with higher wages) Brazilian high-skilled labor market period 1994-2017. highlight importance social skills explaining why growing demand for workers has not been equal across gender. To do so, we built novel Classification Occupations (CBO) rating based on skill content compatible O*NET task index. Our results show po...

Using panel data from 2004 to 2012, we employ a two-step system GMM estimation technique, with robust standard errors, collapsed instruments and illus-trate marginal effects of central bank independence on financial development in Africa. We also examine the moderating roles human capital, proxied by literacy rates CBI-financial nexus. find that, countries higher rates/human positive impact dej...

Grillages are widely used in various structures. In this research, the Colliding Bodies Optimization (CBO) and Enhanced Colliding Bodies Optimization (ECBO) algorithms are used to obtain the optimum design of irregular grillage systems. The purpose of this research is to minimize the weight of the structure while satisfying the design constraints. The design variables are considered to be the c...

In rigid plastic analysis one of the most widely applicable methods that is based on the minimum principle, is the combination of elementary mechanisms which uses the upper bound theorem. In this method a mechanism is searched which corresponds to the smallest load factor. Mathematical programming can be used to optimize this search process for simple fra...
