Abstract

The invention relates to a crop plantation space layout optimization method based on an intelligent optimization algorithm, in particular to a crop plantation space layout optimization method based onan improved Cuckoo algorithm, and belongs to the field of geographic space layout planning. The method aims at a crop plantation layout optimization problem to redefine an individual coding way, an initial layout scheme generation method and a multi-objective function and constraint condition processing method in the Cuckoo algorithm on the basis of a Cuckoo algorithm framework, a one-to-one mapping relationship of the problem and the Cuckoo algorithm is established, and a cross replacement strategy and a local update strategy, which aim at the space layout, are put forward so as to establishthe information exchange and update mechanism of a Cuckoo individual again to meet crop space layout optimization requirements. Meanwhile, the method is combined with a Pareto multi-objective processing technology, and various candidate schemes can be generated to provide decision support for decision makers. By use of the cross replacement and local update strategy put forward by the invention,the convergence efficiency and the solving accuracy of the algorithm are improved.

Description

technical field [0001] The invention relates to a method for optimizing the spatial layout based on an intelligent algorithm, in particular to a method for optimizing the spatial layout of crop planting based on the improved cuckoo algorithm. Background technique [0002] Spatial layout optimization problem is a kind of complex spatial problem that widely exists in the field of geography research. Its basic purpose is to use a certain space search method to obtain specific goals (economic goals, social goals, ecological goals, etc.) and under certain constraints. The optimal spatial entity distribution state of . Many complex spatial problems can ultimately be attributed to the optimization of spatial layout, such as the optimal allocation of land resources, the location of parks or supermarkets, etc., are considered to be classic spatial layout optimization problems. Although this type of problem exists widely in production and life, it is difficult to solve it. The main r...

Problems solved by technology

Although this type of problem exists widely in production and life, it is difficult to solve it. The main reason is that the spatial layout optimization problem is a combinatorial optimization problem that involves spatial information. There are a large number of solutions to the problem to be optimized and a huge solution space. , which is the so-called "combinatorial explosion", and the traditional solution method has high time and space complexity, and it is difficult to solve the above problems

[0012] At present, there is no precedent for the attempt to combine the cuckoo algorithm with the spatial layout optimization problem
