A branch-and-cut-and-price approach for the capacitated m-ring-star problem
(Elsevier Science BvAmsterdamHolanda, 2012)
Diseño topológico de redes : un caso : 2-node-connected star problem
(UR.FI-INCO, 2016)
En este trabajo se propone un nuevo problema de optimización combinatoria que denominamos Two-Node-Connected Star Problem (2NCSP), el cual, dado un grafo simple con costos de ruteo y costos de asignación, tiene como objetivo ...
A Variable Neighborhood Search Approach for the Capacitated m-Ring-Star Problem
In this paper, we proposed an algorithm based on variable neighborhood search (VNS) for the capacitated m-Ring-Star problem. This problem has several real applications in communications networks, rapid transit system ...
Constraining the nature of the possible extrasolar PDS110b ring system
(2021-08-01)
The young star PDS110 in the Ori OB1a association underwent two similar eclipses in 2008 and 2011, each of which lasted for a period of at least 25 days. One plausible explanation for these events is that the star was ...
The capacitated m two node survivable star problem
(UR. FI – INCO., 2015)
The problem addressed in this paper attempts to efficiently solve a network design with redundant connections, often used by telephone operators and internet services. This network connects customers with one master node ...
Estudo da estabilidade de anéis em exoplanetas
(Universidade Estadual Paulista (Unesp), 2019-03-08)
A estrela PDS110 (HD290380) com idade aproximada de 10 milhões de anos, apresentou dois eclipses ocorridos em 2008 e 2011, com duração de 25 dias e queda de aproximadamente 26 % na luminosidade da estrela. Outra estrela ...
