Algorithm 1 Pseudo-code of ISMA

Initialize the parameters popsize, Max_iteraition

Initialize the positions of the slime mould

While (t ≤ Max_iteraition)

Calculate the fitness of all the slime mould

Update bestFitness, Xb

Calculate the W by Equation (4)

For each search portion,

Update p by Equation (8)

Update positions by Equation (9)

End For

t = t + 1

End While

Return bestFitness, Xb
