White Blood Cell Segmentation by Circle Detection Using Electromagnetism-Like Optimization

Algorithm 1

[EMO (𝑁,𝑀𝐴𝑋𝐼𝑇𝐸𝑅,𝐼_𝑙,𝛿)].

(1) Input parameters: the maximum number of iterations MAXITER, the values for the local

 search parameters such as 𝐼_𝑙 and 𝛿, and the size 𝑁 of the population are all defined.

(2) Initialize: set the iteration counter 𝑘=1, initialize the members of 𝑆_𝑘 uniformly in 𝑋,

 and identify the best point in 𝑆_𝑘.

(3) while 𝑘<𝑀𝐴𝑋𝐼𝑇𝐸𝑅 do

(4) 𝐹^𝑘_𝑖←Calc𝐹(𝑆_𝑘)

(5) 𝑦_𝑖,𝑘 = Move (𝑥_𝑖,𝑘,𝐹^𝑘_𝑖)

(6) 𝑧_𝑖,𝑘= Local (𝐼_𝑙,𝛿,𝑦_𝑖,𝑘)

(7) 𝑥_𝑖,𝑘+1 = Select (𝑆_𝑘+1,𝑦_𝑖,𝑘,𝑧_𝑖,𝑘)

(8) End while
