bug in disc brake design problem

[linjunhe]

In the supplementary file and the source codes, the constraint on x4 is miscalculated as 11 <= x4 <= 20, but it should be 2 <= x4 <= 11.

Thank you for pointing out the bug and typo. Yes, I made a miscalculation. The range of $x_4$ should be [2, 11].

Sir, RE24 CODE IN MATLAB VERSION, sigmaB = 4500 / (x1 * x2); maybe BOTH X1 and X2 are ZERO, SO THERE IS NAN IN YOUR OBJECTIVES.

Thanks for your comment. But, it will only occur if x1 and x2 violate the bound constraints [0.5, 4] and [4, 50], respectively.

Thanks you, sir: &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Then if i remember it rightly. the bug probably happened in RE22.m, code: g(1) = (x1 * x3) - 7.735 * ((x1 * x1) / x2) - 180.0; main.m specifies bounds of x2 within [0,20],so i set the x2 within [0.000001,20], the bug is OK. Good lucky. Leenstead ***@***.*** &nbsp;
