Abstract

The invention relates to an improved wolf pack algorithm based on firework explosion behaviors, belongs to the technical field of robot path planning, and aims to reduce the exploration pace of exploded fireworks close to a prey and improve the local exploration capability by introducing the exploration rule of the exploded fireworks of a fireworks algorithm, and increase the search radius of theprey far away from the prey and improve the global search capability. The moving step length of the running behavior is improved, the step length is automatically adjusted according to the position ofeach wolf, and the running behavior efficiency is improved. And the updating rule of the wolf pack algorithm is improved, and wolf pack individuals are selected and eliminated according to probabilities, so that the global optimization capability of the algorithm is enhanced. The method has the advantages of high convergence speed and high convergence precision.

Description

technical field [0001] The invention belongs to the technical field of robot path planning, and in particular relates to an improved wolf pack algorithm based on the explosion behavior of fireworks. Background technique [0002] Path planning is the key technology for mobile robots to realize autonomous navigation. Mobile robot path planning is a method to find a feasible and collision-free path problem in a mobile environment. At present, path planning methods can be mainly divided into traditional path planning methods and path planning algorithms using swarm intelligence algorithms. Traditional path planning algorithms, such as A * Algorithm, D * Algorithms and artificial potential field methods; swarm intelligence algorithms include genetic algorithms, ant colony algorithms, artificial fish swarm algorithms, particle swarm algorithms, and wolf swarm algorithms. Since the swarm intelligence algorithm is based on the probability search algorithm, it has the advantages o...
