METAHEURISTIC ALGORITHMS FOR MINIMUM CROSSING NUMBER PROBLEM
This paper presents the application of metaheuristic methods to the minimum crossing number problem for the first time. These algorithms including particle swarm optimization, improved ray optimization, colliding bodies optimization and enhanced colliding bodies optimization. For each method, a pseudo code is provided. The crossing number problem is NP-hard and has important applications in eng...
متن کاملNut Production in Bertholletia excelsa across a Logged Forest Mosaic: Implications for Multiple Forest Use
Although many examples of multiple-use forest management may be found in tropical smallholder systems, few studies provide empirical support for the integration of selective timber harvesting with non-timber forest product (NTFP) extraction. Brazil nut (Bertholletia excelsa, Lecythidaceae) is one of the world's most economically-important NTFP species extracted almost entirely from natural fore...
متن کاملConstruction of Brazil nut (Bertholletia excelsa: Lecythidaceae) cambium normalized cDNA libraries for 454 next generation sequencing
Background The Brazil nut, Bertholletia excelsa (Lecythidaceae), is the most important non-timber forest resource in the Amazonian biome, where nuts for the international trade are exclusively wild-collected. The monotypic genus possesses a discontinuous distribution and is thought to have rapidly and recently radiated south and westward from a northern/eastern Amazonian origin, largely as a re...
متن کاملIsolation and characterization of microsatellite markers for Bertholletia excelsa (Lecythidaceae) population genetic analysis.
Seven polymorphic microsatellite markers were developed and validated for Bertholletia excelsa (Brazil nut tree) population genetic studies. This species is a widespread monotypic Amazonian tree with high non-timber economic value. Unfortunately, Brazil nut production is currently less than 25% of historical production levels, because of extensive deforestation. All pairs of primers produced cl...
متن کاملContemporary pollen and seed dispersal in natural populations of Bertholletia excelsa (Bonpl.).
Due to the nutritional content and commercial value of its seeds, Bertholletia excelsa is one of the most important species exploited in the Amazon region. The species is hermaphroditic, insect pollinated, and its seeds are dispersed by barochory and animals. Because the fruit set is dependent on natural pollinator activity, gene flow plays a key role in fruit production. However, to date, ther...
