Hi,

You can try using BLEAQ2 algorithm, the code for which is available on matlab:

I have a two-level programming model, can you help me with an algorithm code BLEAQ2 in programming the model and finding the final solution?

minF(S1,S2)=1.25*S1^2+4*S2^2

minf(s1,s2)=s1^2+6*s2^2

s.to 2*s1^2+0.6*s2^2 <= 5100000

3*s1^2+4*s2^2 <= 6100000

Otsu's method?

mean() ?

could you send any link for this method

"The graythresh function uses Otsu's method, which chooses the threshold to minimize the intraclass variance of the black and white pixels."
