Due to the weak nature of agricultural production, governments usually adopt supportive policies protect food security. To discern growth agriculture from 2001 2018 under China’s support policies, we use nonlinear MS(M)-AR(p) model distinguish economic cycle into three regimes—rapid, medium, and low—and analyze probability shifts maintenance among different regimes. We further calculated averag...

Abstract We measure the environmental dependence, where environment is defined by distance to third nearest neighbor, of multiple galaxy properties inside Environmental COntext (ECO) catalog. focus primarily on void galaxies, which we define as 10% galaxies having lowest local density. compare and non-void galaxies: baryonic mass, color, fractional stellar mass growth rate (FSMGR), morphology, ...

A rule selection scheme of evolutionary algorithm is proposed to design fuzzy path planner for shooting ability in robot soccer. The fuzzy logic is good for the system that works with ambiguous information. Evolutionary algorithm is employed to deal with difficulty and tediousness in deriving fuzzy control rules. Generic evolutionary algorithm, however, evaluate and select chromosomes which may...

Inverse Combinatorial Optimization has become a relevant research subject over the past decades. In graph theory, the Inverse Shortest Path Length problem becomes relevant when people don’t have access to the real cost of the arcs and want to infer their value so that the system has a specific outcome, such as one or more shortest paths between nodes. Several approaches have been proposed to ta...

In this paper, an evolutionary approach to solve the mobile robot path planning problem is proposed. The proposed approach combines the artificial bee colony algorithm as a local search procedure and the evolutionary programming algorithm to refine the feasible path found by a set of local procedures. The proposed method is compared to a classical probabilistic roadmap method (PRM) with respect...

The paper presents Greedy Randomized Adaptive Search Procedure with Path Relinking (GRASP with PR) for the Critical Node Detection Problem (CNDP). An evolutionary Path Relinking mechanism is added to GRASP with PR to intensify. Our computational experiments show that this algorithm is a competitive method compared with the previously proposed methods for solving CNDP such as Variable Neighborho...
