HGSO mimics the behavior governed by Henry’s law to solve challenging optimization problems. Henry’s law is an essential gas law relating the amount of a given gas that is dissolved to a given type and volume of liquid at a fixed temperature. The HGSO algorithm imitates the huddling behavior of gas to balance exploitation and exploration in the search space and avoid local optima.
Henry’s law was first proposed in 1800 by J.W. Henry, which is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. In others words, the maximum quantity of solute that can dissolve in a specific quantity of solvent at a specified temperature or pressure is called solubility. HGSO inspired by the behavior of Henry’s law.
