Engineering Contradiction Analysis
1Reliability
If existing particle swarm optimization techniques are used, then the optimization process can be performed, but the convergence is sub-optimal and lacks consistency
Solution Approach 1:
The particle swarm is segmented into multiple sub-swarms, each exploring different regions of the search space independently. This segmentation allows diverse exploration strategies to be applied simultaneously, improving both convergence consistency and solution accuracy by preventing premature convergence to sub-optimal solutions.
Solution Approach 2:
The invention dynamically changes key parameters including inertia weight, cognitive coefficient, and social coefficient during the optimization process. These parameter variations adapt the swarm's behavior to balance exploration and exploitation phases, ensuring consistent convergence while maintaining high solution accuracy across different problem instances.
2Adaptability or versatility
If existing meta-heuristic techniques are used, then optimization problems can be solved, but the techniques lack desirable diversification
Solution Approach 1:
The invention applies preliminary actions by implementing multiple initialization strategies and preprocessing steps that prepare the swarm for diverse exploration. Random initialization, grid-based initialization, and problem-specific initialization methods are used to ensure the swarm starts with adequate diversity, which maintains high success rates while enabling comprehensive search space exploration.
Solution Approach 2:
The invention introduces additional dimensions to the optimization process by incorporating multiple objective functions, constraint handling mechanisms, and hybridization with other optimization algorithms. This multi-dimensional approach enhances diversification capabilities while maintaining reliable convergence through coordinated exploration across different dimensions.
3Ease of operation
If existing optimization techniques are used, then the process can proceed, but complexity increases due to trial and error parameter tuning
Solution Approach 1:
The optimization algorithm implements self-service through automatic parameter tuning mechanisms that adjust inertia weight, cognitive coefficient, and social coefficient based on the optimization progress and problem characteristics. This self-adjusting capability eliminates the need for manual trial and error parameter tuning, significantly simplifying operation while maintaining optimal performance across different problem types.
Solution Approach 2:
The invention automatically changes parameters based on iteration count, swarm distribution, and convergence metrics. The inertia weight decreases while cognitive and social coefficients adjust dynamically, providing a systematic parameter evolution strategy that reduces operational complexity by replacing manual tuning with automated adaptive parameter management.
4Measurement precision
If existing techniques are used, then optimization can be performed, but exploration of search space is experimental rather than theory-based
Solution Approach 1:
The invention implements comprehensive feedback mechanisms that monitor swarm distribution, convergence metrics, and exploration efficiency at each iteration. This feedback drives theory-based adjustments to particle velocities, position updates, and parameter settings, ensuring accurate solutions are found efficiently without relying on experimental trial and error approaches.
Solution Approach 2:
The optimization process dynamically adapts its exploration and exploitation behavior based on theoretical convergence criteria and real-time performance metrics. The swarm transitions smoothly between exploration-dominated early phases and exploitation-dominated later phases, reducing convergence time while maintaining high solution accuracy through theory-guided dynamic adjustment.

AI summary
A system and method for determining an optimal solution to an optimization problem in a swarm of candidate solutions is provided. The invention comprises generating a population of random particles, where each particle is representative of a candidate solution. Further, a best particle is identified from the generated population of particles. The best particle is representative of an optimal solution. The population of particles is categorised into similar and non-similar particle groups by applying one or more multivariate measurement techniques, and similarity between the particles of the non-similar particle group with best particle is updated by applying an imitation technique. The generated population is updated with updated particles and a new best particle is evaluated from said population. Furthermore, final best particle is determined by further updating the population of particles until one or more target conditions are achieved.
