I mean something like:
I have to solve a Knapsack problem in my application
I describe an XML with all variables, objectives and more
I Upload this XML to a remote server (via a restful API)
I get back as response just the result, XML-formatted
With a solution like this, i do not need to install AMPL on my server and try to do communicate my app with AMPL.
It exist? Otherwise, do you thinks that could be useful?
