Proposta de mensuração de risco baseado em utilidade Risk measurement proposal based on utility

Autor: Rodrigo Leone, Roberto Quirino do Nascimento, George Guerra Leone, Paulo Oliveira

Publikováno v: Revista Contabilidade & Finanças, Vol 18, Iss 44, Pp 23-32 (2007)

A mensuração do risco, integrada aos modelos de finanças corporativas mediante o trabalho de Markowitz, era baseada na variância dos retornos em torno do retorno médio naquele período. Entretanto, apesar do cálculo do risco pela variância ter

A Branch-and-Bound Algorithm for the Close-Enough Traveling Salesman Problem

Autor: Roberto Quirino do Nascimento, Artur Alves Pessoa, Anand Subramanian, Walton Pereira Coutinho

Publikováno v: INFORMS Journal on Computing. 28:752-765

This paper addresses the close-enough traveling salesman problem. In this problem, rather than visiting the vertex (customer) itself, the salesman must visit a specific region containing such vertex. To solve this problem, we propose a simple yet eff

Publikováno v: Journal of Heuristics. 22:365-382

Several papers in the scientific literature use metaheuristics to solve continuous global optimization. To perform this task, some metaheuristics originally proposed for solving combinatorial optimization problems, such as Greedy Randomized Adaptive

A continuous strategy to solve a class of mixed optimization problems

Autor: Roberto Quirino do Nascimento, Rubia Mara de Oliveira Santos, Edson Figueiredo Lima

Publikováno v: Discrete Applied Mathematics. 164:264-275

This work presents a method to solve a class of discrete optimization problems, including linear, quadratic, convex, and discrete geometric programming problems. The methodology consists of inserting, in the original problem, additional geometric con

The discrete ellipsoid covering problem: A discrete geometric programming approach

Autor: Lucídio dos Anjos Formiga Cabral, Ana Flávia Uzeda dos Santos Macambira, Renan Vicente Pinto, Roberto Quirino do Nascimento

Publikováno v: Discrete Applied Mathematics. 164:276-285

The ellipsoid covering problem consists of covering an ellipsoid with spheres whose radii belong to a discrete set. The discrete nature of the radii of the spheres is one of the difficulties inherent to solving this problem. The other difficulty is t

A Continuous Strategy to Solve a Class of Discrete Optimization Problems

Autor: Rubia Mara de Oliveira Santos, Edson Figueiredo Lima, Roberto Quirino do Nascimento

Publikováno v: Electronic Notes in Discrete Mathematics. 36:279-286

In this work we develop a method to solve a class of discrete optimization problems. This class covers linear, quadratic, convex, and discrete geometric programming problems. The methodology consists in inserting additional geometric constraints wher
