Correction of Faulty Sensors in Phased Array Radars Using Symmetrical Sensor Failure Technique and Cultural Algorithm with Differential Evolution

Pseudocode 1

The pseudocode of the differential evolution algorithm.

Generate the initial population of individuals

Do

 For each individual 𝑗 in the population

 Choose three numbers 𝑛₁,𝑛₂,  and   𝑛₃  that is,   1≤𝑛₁,𝑛₂,𝑛₃≤𝑁 with 𝑛₁≠𝑛₂≠𝑛₃≠𝑗

 Generate a random integer 𝑖_rand∈(1,𝑁)

 For each parameter 𝑖

    𝑦^𝑖,𝑔=𝑥^𝑛1,𝑔+𝐹(𝑥^𝑛2,𝑔−𝑥^𝑛3,𝑔)

    𝑧_𝑗^𝑖,𝑔=𝑦_𝑗^𝑖,𝑔𝑖𝑓rand()≤CR𝑜𝑟𝑗=𝑗_rand𝑥_𝑗^𝑖,𝑔otherwise

  End For

  Replace 𝑥^𝑖,𝑔 with the child 𝑧^𝑖,𝑔 if 𝑧^𝑖,𝑔 is better

End For

Until the termination condition is achieved
