I am trying to understand the difference, if any, between feasible, possible and potential. Most online dictionaries report them as synonyms. Is this right?
More specifically, I want to use these terms in the context of a maximization problem (that is a mathematical problem where a user-defined function should be maximized with respect to some input variables). Referring to all the input combinations of the function, which term should I use? Or is it simply a matter of style?
The phrase reads:
The variables define the search space which includes all the … voltage patterns.
*I control the voltage patterns. The goal is to find the voltage pattern that maximizes my function.
P.S. I have also encountered the term candidate solutions to describe the possible solutions.

In some contexts feasible and possible have very similar meanings.
I would see both of these as conveying the same idea.
I would use feasible when I have a more specific goal:
the defining characteristic being implications of the duration of journey and scheduling of a suitable service, and availability of seats. The conditionality being intrinsic to the course of action.
I would use possible when the constraints are not just the travel but also my own availability (and perhaps being somewhat evasive) my own preference.
Possible also has connotations of situations that arise outside my control.
I don't think we would say
Potential doesn't seem quite to fit any of those scenarios, butI think in general it has a feeling of the unrealised, of a specific thing that has yet to happen and may not, it may for ever be unrealised.
I mention the above to give a flavour the nuances that separate these synonyms.
In your context we are talking about voltage patterns, and I can see merit in all three
In your sentence my instinct is:
Potential is less good because I don't believe it works well when dealing with a wide range of outcomes, and trivially, because Potential Difference is a synonym for Voltage.
Feasible seems technically correct, in that the real determinant of the candidate set of patterns is your ability to create them, its under your control, it's what you are capable of "making" as in the etymology of Feasible from the French "faire".
However I would use Possible, as I think this is a theoretic problem where you will calculate answers to specified inputs and may never actually "make" anything at all.
