Association Rule Mining (ARM) technique that attempt to unearthing interesting pattern or relationship between data in large database. Genetic Algorithm (GA) is a search heuristic which is used to generate useful solution for optimization and search problems. Genetic Algorithm (GA) based evaluation in mining technique is backbone for mining interesting rule based on GA parameters like fitness function, crossover rate, and mutation rate. The key focus of this synthesize approach is to optimize the rule that generated by mining methodology and to provide more accurate results. Many researches has been carried out in this area, this paper is to represents the survey on genetic algorithm & fundamentals.
