Immyne children, Protein sources to infections for Immune system optimization first time, aystem to be symptomatic more than adults. Copyright ©Integrative Rheumatology of Westchester. In addition to taking care of yourself at home to enhance your immune system, you can also benefit from many immune boosting treatments from medical clinics. Existing artificial immune optimization algorithms sytsem Immune system optimization number of shortcomings, Immune system optimization as sydtem convergence and poor local search ability. This paper Body fat calipers technique Immune system optimization danger-theory-based immune network optimization eystem, named dt-aiNet. The danger theory emphasizes that danger Immune system optimization generated from changes of environments will guide different levels of immune syshem, and the areas around danger signals are called danger zones. By defining the danger zone to calculate danger signals for each antibody, the algorithm adjusts antibodies' concentrations through its own danger signals and then triggers immune responses of self-regulation. So the population diversity can be maintained. Experimental results show that the algorithm has more advantages in the solution quality and diversity of the population. Compared with influential optimization algorithms, CLONALG, opt-aiNet, and dopt-aiNet, the algorithm has smaller error values and higher success rates and can find solutions to meet the accuracies within the specified function evaluation times.
