Neural Network Path Planning Using Energy Functions

The application of energy functions in neural network path planning represents an intelligent algorithm that introduces physical energy concepts into robotic motion decision-making. This method constructs virtual energy fields to simulate environmental obstacles and path constraints, enabling autonomous optimal path discovery. In code implementation, this typically involves creating an energy matrix where obstacle coordinates are assigned high potential values while the target location receives the lowest energy level.

The core concept transforms path planning into an energy minimization problem. In 3D space, obstacles are modeled as high-energy regions while the target point corresponds to an energy valley. The neural network learns to avoid high-energy areas through continuous weight adjustments, eventually converging to the lowest-energy safe path. Algorithmically, this involves implementing gradient descent or backpropagation to update neuron weights based on energy field feedback.

The integration of simulated annealing effectively addresses the neural network's tendency to fall into local optima. By gradually reducing the system "temperature," the algorithm balances global exploration and local optimization, significantly improving path planning success rates. Code implementation requires maintaining a temperature parameter that controls acceptance probabilities for suboptimal solutions during iteration cycles.

In practical applications, the routine typically comprises three key modules: the environment modeling module converts physical space into energy fields using spatial mapping functions, the neural network module handles path optimization through multilayer perceptron architectures, and the annealing control module regulates search strategies with temperature scheduling algorithms. This bio-inspired planning approach demonstrates superior dynamic environment adaptability and computational efficiency compared to traditional algorithms, particularly in complex 3D scenarios with multiple obstacles or rugged terrain.
