The brain storm optimization algorithm is a

heuristic algorithm A heuristic or heuristic technique (''problem solving'', '' mental shortcut'', ''rule of thumb'') is any approach to problem solving that employs a pragmatic method that is not fully optimized, perfected, or rationalized, but is nevertheless ...

. More than 200 papers related to BSO algorithms have appeared in various journals and conferences. There have also been special issues and special sessions on Brain Storm Optimization algorithm in journals and various conferences, such as Memetic Computing Journal. There are a number of variants of the algorithms as well, such as Hypo Variance Brain Storm Optimization, where the object function evaluation is based on the hypo or sub variance rather than Gaussian variance, and Global-best Brain Storm Optimization, where the global-best incorporates a re-initialization scheme that is triggered by the current state of the population, combined with per-variable updates and fitness-based grouping.

quantum In physics, a quantum (: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a property can be "quantized" is referred to as "the hypothesis of quantization". This me ...

local optimum In mathematical analysis, the maximum and minimum of a function are, respectively, the greatest and least value taken by the function. Known generically as extremum, they may be defined either within a given range (the ''local'' or ''relative' ...

). A number of comparison studies are conducted between PSO and BSO. Recently published book contains much more up to date references. It was used to design 5G network as well.
