17. The method of claim 16 , further comprising configuring a maintenance repair procedure in response to determining that the current number of relaxed constraints is below the predetermined threshold.
16. The method of claim 15 , in response to determining that the predicted product output for each learned relationship in the set of learned relationships does not satisfy output constraints, further comprising: relaxing a set of output constraints; and extracting recipe parameters for the adjusted recipe based at least in part on the received set of learned functions or the received input material measurements in response to determining that a current number of relaxed constraints is below a predetermined threshold.
