Lingo solves the maximum (small) value of piecewise function

problem solving ：

lingo The code is as follows ：

model:
@bnd(33,x1,200);%x1 yes 33~200 Number between
@bnd(0.5,x2,5);
@bnd(33,x3,200);
@bnd(0.3,x4,2.1);
@gin(x5); %x5 Is an integer
@bnd(250,x5,350);
max=13436.16-33.738*x1-86.924*x5-211.18*x2*x2+0.147*x5*x5+3.568*x3*x4+0.113*x1*x5-3.519*x4*x5+614.597*x2*x4;% The expression is different , Because the result of the above formula is very strange
end

lingo It is still very simple to solve the maximum value problem of piecewise functions , It only takes a few lines of code to solve the problem .

over!!!
