1Use of energy by moving object
If traditional computational methods are used to model a plurality of random walkers, then computational accuracy can be maintained, but electrical power consumption increases and computational efficiency decreases
Solution Approach 1:
The patent replaces traditional von Neumann architecture with a neuromorphic computing system that mimics biological neural networks. Spiking neurons and synapses are used to naturally encode and process random walker trajectories, eliminating the need for traditional mechanical computation cycles and reducing power consumption while maintaining or improving computational efficiency.
Solution Approach 2:
The system changes the computational representation from continuous numerical values to discrete spiking events. Random walker positions and movements are encoded as sequences of neural spikes with specific timing and patterns, fundamentally altering the parameter space and enabling more energy-efficient processing.
2Temperature
If traditional computational methods are used to model a plurality of random walkers, then computational accuracy can be maintained, but heat output increases and equipment efficiency reduces
Solution Approach 1:
The neuromorphic system replaces traditional high-heat-generating computational hardware with biologically-inspired circuits that operate at lower temperatures. The event-driven spiking neural network architecture reduces unnecessary computational activity, thereby reducing heat generation and improving equipment reliability.
3Loss of time
If traditional computational methods are used to model a plurality of random walkers, then computational accuracy can be maintained, but computational time increases
Solution Approach 1:
The spiking neural network uses periodic spiking patterns to represent and update random walker positions. Instead of continuous computation, the system uses discrete periodic events (spikes) to propagate information, reducing computational time while maintaining simulation accuracy through the temporal coding of positional information.
Solution Approach 2:
The neuromorphic system maintains continuous simulation of random walker dynamics through persistent neural activity patterns. Spiking neurons continuously update walker positions in real-time without the need for discrete computational cycles, eliminating idle time and maintaining accuracy throughout the simulation.

AI summary
A method for increasing a speed or energy efficiency at which a computer is capable of modeling a plurality of random walkers. The method includes defining a virtual space in which a plurality of virtual random walkers will move among different locations in the virtual space. The method also includes either assigning a corresponding set of ringed neurons in a spiking neural network to a corresponding virtual random walker, or assigning a corresponding set of ringed neurons to a point in the virtual space. Movement of a given virtual random walker is tracked by decoding differences between states of individual neurons in a corresponding given set of ringed neurons. A virtual random walk of the plurality of virtual random walkers is executed using the spiking neural network.
