Table 2

Semi-code of gravitational algorithm.

(1) Determining system area and initial valuing
(2) Initial positioning OF the masses
(3) Evaluating THE masses
(4) Updating parameters G, best, worst, and 𝑀
(5) Calculating delivered force on each mass
(6) Accounting acceleration and speed of each mass
(7) Updating position of masses
(8) If stop condition does not meet, go to phase 3
