1 简介

PO 是由巴基斯坦国立计算机和新兴科学大学的 Qamar Askari 等人于 2020 年提出的一种受社会启发的新型全局优化算法，灵感来源于政治的多阶段过程。该算法通过将种群从逻辑上划分为政党和选区，赋予每个解双重角色，便于每个候选人更新政党领袖和选区获胜者的位置。

for a=1:areas

    newAWinner = aWinners(a,:);

    i = aWinnerInd(a);    

    

    toa = randi(areas);

    while(toa == a)

        toa = randi(areas);

    end

toAWinner = aWinners(toa,:);

    for j = 1:dim

        distance = abs(toAWinner(1,j) - newAWinner(1,j));

        newAWinner(1,j) a= toAWinner(1,j) + (2*rand()-1) * distance;

    end

    newAWFitness=fobj(newAWinner(1,:));

    

%Replace only if improves

if newAWFitness < fitness(i) 

        Positions(i,:) = newAWinner(1,:);

        fitness(i) = newAWFitness;
