for step profile of heat flux. The results clearly indicate that for step heat flux profile,
RMS error for simple JAYA, multi-population-based JAYA and modified JAYA algorithm is 149.75, 244.0194 and 8.821 × 10
–5 , respectively, which means that modified
JAYA algorithm has the highest accuracy compared to others. Figures 7, 8 and 9 are
similar results derived for smooth, linear and triangular profiles, respectively. For
every considered profile, modified JAYA algorithm is proved with more accurate
results. Computational time of modified JAYA algorithm is higher compared to other
two algorithms.
