Naming multiple variables in highspy

[mocenigo]

I would like to know how to five give an explicit name (instead of c_ekk) to variables indexed by parameters, such as

h = highspy.Highs()
A1 = h.addBinaries(5,64)

For instance, something like

A1 = h.addBinaries(5,64,name=f"pippo_{first}_{second}")

so that when writing the LP program to a file, I would see names like pippo_1_13, pip_0_61, and so on instead of many c_ekk1375 and so on.

I can do this for individual variables, but I wonder whether there is a faster way instead of implementing it myself in a separate routine using AddVariable

The best I can suggest is

h = highspy.Highs()
x = h.addBinaries(5, 64, name_prefix="pippo_")
for i in range(5):
for j in range(64):
print(x[i,j].name)

which gives

pippo_(0,0)
pippo_(0,1)
pippo_(0,2)
pippo_(0,3)
pippo_(0,4)
pippo_(0,5)
pippo_(0,6)
...
pippo_(4,59)
pippo_(4,60)
pippo_(4,61)
pippo_(4,62)
pippo_(4,63)
