Thank you for raising this, @dkatz23238! Currently working on this, actually : ) We'll include 2+ parameter constraints with the upcoming version. It's not at all a system limitation, it's just how the string parsing is currently organized for the Service API.
As for an equality constraint ("x1 + x2 == 1.0" as opposed to "x1 + x2 >= 1.0"), that's a bit of a different story, as tight constraints like that may pose a difficulty in some of the modeling. One solution would be to optimize over a subspace: to only include x1 into your search space, and set x2=1-x1
in evaluation? Similarly, if you had 3 parameters: x1, x2, and x3 –– you could include x1 and x2 into the search space, and set x3=1-(x1+x2)
when evaluating trials.

Thanks for the smart work around I will try them out!.
Should I close this issue since this feature is already planned?

@dkatz23238, let's not close this just yet, until the fix is in the repo : ) Thank you!

Fix for sum constraints of 3+ parameters is now on master! We are planning on releasing a new stable version towards the end of the week, so it will be in then; for now, if it's urgent, you could try to build from master.

Closing, since this should be in our current release (0.1.2)!
