This message is generated when the indicated function did not find any points that satisfy the constraints.
This error can occur if the constraints are inconsistent, or if the procedure used to find starting values for the variables does not find starting values that satisfy the constraints.
Off[message] switches off the message; On[message] switches it on. For example: Off[NMinimize::incst].
Examples
Basic Examples(1)
A warning is generated because NMinimize uses a starting value that does not satisfy the constraint:
This error can typically be avoided by providing starting values for the variable:
