When I give a range for the variables, and ask Canvas to generate variable-solution combinations, it does that. But, often, there are repeated combinations. (And I'd like to delete the duplicates.) Secondly, there are some particular variable choices I don't want. For example, I want a range for the variable from -5.25 to + 5.25, but if one of the choices selected by Canvas is 0, I want to also delete that combination. And, after the choices are generated, I want to possible add more variable choices. How can I do that?
If that's not possible, I'm fine with giving my own sets of variables and having Canvas generate the solutions. Is that possible?
