An Improved Quantum-Inspired Genetic Algorithm for Image Multilevel Thresholding Segmentation

Pseudocode 1

Pseudocode for cooperative learning strategy.

Choose 𝑚  𝑛-dimensional individuals

Repeat:

 For each individual 𝑞_𝑖 with fitness 𝑓_𝑖   𝑖∈[1,𝑚]

  For each dimension 𝑗∈[1,𝑛]

   𝑞_𝑖𝑗=(𝑞_𝑖1,…,𝑞_𝑏𝑗,…,𝑞_𝑖𝑛)

   Evaluate 𝑞_𝑖𝑗 and store its fitness 𝑓_𝑖𝑗

  Endfor

  𝑓^′_best=max(𝑓_𝑖𝑗)

  𝑞^′_𝑖𝑏set=argmax(𝑓_𝑖𝑗)

  If 𝑓^′_best>𝑓_𝑖

   𝑞_𝑖=𝑞^′_𝑖best

  Endif

 Endfor

Until termination criterion is satisfied
