Simultaneous Heat Transfer Search

Single Objective Heat Transfer Search (Termination Criterion: Number of iterations)

Simultaneous Heat Transfer Search is a single objective optimization technique for unconstrained problems. Unlike the Heat Transfer Search which uses only one mode of heat transfer in a single iteration, SHTS divides the population and utilizes simultaneous heat transfer through all the three modes. Other major differences with HTS can be obtained from the following references.

Note:
(i) If N is the size of the population, exactly N functional evaluations are required in a complete iteration of SHTS. If there are T iterations, then the total number of functional evaluations will be NT + N. This is because NT evaluations are required for all the iterations and the N population members are to be evaluated before the start of the iteration.
(ii) SHTS has two user defined parameters, viz., (i) Population Size and (ii) the number of iterations (or an alternate termination criterion).
(iii) SHTS is monotonically convergent.
(iv) SHTS required the population size to be an integral multiple of 6. However this implementation eliminates this restriction by appropriately dividing the population.
