%%?%%%%%%%%%%%%%用ABC算法優化SVM中的參數c和g開始%%%%%%%%%%%%%%%%%%%%
%%?參數初始化
NP=20;?%?蜂群規模
FoodNumber=NP/2;?%?蜜源（解）數量
limit=100;?%?當有蜜源連續沒被更新的次數超過limit時，該蜜源將被重新初始化
maxCycle=10;?%?最大迭代次數
%?待優化參數信息
D=2;?%?待優化參數個數，次數為c和g兩個
ub=ones（1D）*100;?%?參數取值上界，此處將c和g的上界設為100
lb=ones（1D）*（0.01）;?%?參數取值下界，此處將c和g的下界設為0.01

runtime=2;?%?可用于設置多次運行（讓ABC算法運行runtime次）以考察程序的穩健性
??
BestGlobalMins=ones（1runtime）;?%?全局最小值初始化?，這里的優化目標為SVM預測結果中的平均平方誤差（MSE），初始化為最差值1
BestGlobalParams=zeros（runtimeD）;?%?用于存放ABC算法優化得到的最優參數

for?r=1:runtime?%?運行ABC算法runtime次?
????%?初始化蜜源
????Range?=?repmat（（ub-lb）[FoodNumber?1]）;
????Lower?=?repmat（lb?[FoodNumber?1]）;
????Foods?=?rand（FoodNumberD）?.*?Range?+?Lower;

????%?計算每個蜜源（解）得目標函數值，objfun為計算SVM預測的平均平方誤差（MSE）的函數，根據自己的實際問題變異目標函數即可
????ObjVal=ones（1FoodNumber）;?
????for?k?=?1:FoodNumber
????????ObjVal（k）?=?objfun（Foods（k:）train_data_labelstrain_datatest_data_labelstest_data）;
????end
????Fitness=calculateFitness（ObjVal）;?%?計算適應度函數值
????
????trial=zeros（1FoodNumber）;?%?用于記錄第i個蜜源有連
