Alzheimer disease (AD) is the most common form of dementia. To find a way of cure it, gene study is necessary. And gene order is a new conception of gene study currently, where gene order refers to a permutation of genes in which similar genes are ordered together one by one, and optimal gene order can be abstracted as shortest TSP route. Currently only two types of tools are reported to calculate...
To find all extreme points of multimodal functions is called extreme problem, which is a well known difficult issue in optimization fields. Applying the ant colony optimization (ACO) to solve this problem is rarely reported. The method of applying ACO to solve extreme problem is explored in this paper. Experiments show that the method presented in this paper generates solution with high quality, and...
A group of expression levels of gene generated by gene chips is represented by a vector. The smaller the distance of two vectors is, the more similar the two associated genes are. Gene order is the permutation of genes in which similar genes cluster together, which is useful for biologist. And the optimal gene order is equivalent to the shortest route of traveling salesman problem (TSP), in which...
Spaceborne SAR interferometry (InSAR) is a well known microwave remote sensing technique which has been applied for topography mapping and ground motion monitoring by exploiting phase difference from SAR data acquisition with relevant large spatial scale and high precision. The developed Permanent Scatterers Interferometry (PSI) is a further step of InSAR technique which offers a convenient processing...
