Hello,Andrew:
My name is Zheng Zhipeng,I am a student from China,these days I am
using the GUSEk program.
There are some problems I don't know to handle.First,when I use the
CSV file to store the data,I defined the sets and parameters,but when I
run GUSEK,it told me that :duplicate tuple (4023,20,4136,4022,9715)
detected.in fact ,there is only one (4023,20,4136,4022,9715) in the CSV
file ,so I have to delete it ,it can run successfully,but sometimes I
need this data .
Second ,if I want to solve the least-absolute-deviation problem using
gusek,how should I convert the objective function.My objective function
is following:
sum{a in A,c in C}|(sum{i in I,j in J}
pl[i,j,a,c]*d[i,j]-col[a,c])|
+sum{a in A,b in B,c in C}|(sum{i in I,j in J}
pls[i,j,a,b,c]*d[i,j]-cot[a,b,c])|
+sum{i in I,j in J}|(d[i,j]-dt[i,j])|.
There is an attachment which is my GUSEK code ,if you can help me check
the error I mentioned previous,it will be a great help for me.Thank you
very much!
Your Sincerely
