example sheet table to optimize with names of cells for solver
I know that it is not possible to save a solver model in Calc.
I try to propose a possible solution: I used WPS Office 2016 free, and I noticed that it stores the Solver data in the Definition of cells names.
This technique seems simple enough to implement, so can satisfy the requests of many users.
I attach file that I have produced, with an example sheet table to optimize.
You can see names of cells when press CTRL-F3.
I think it is not difficult for developers to understand.
Hope this proposal can help make this program better.
I apologize, I moved my question here:
