It connects providers of financial information in the cryptocurrency space with investors, providing foresight into market inefficiencies and opportunities. The outcome of the simulation delivers a pareto surface, also referred to as a pareto frontier, that describes a series of optimal design choices that are plotted graphically. The primary use of the pareto chart is to check for one more significant effect that was not obvious on the halfnormal plot. The approach of visualizing the pareto frontier has been widely used in decisionmaking for two and three objective problems. In multiobjective optimization, when the different objectives are contradictory, an optimal solution is said pareto optimal when it is not possible to improve an objective without degrading the others.
