Solution Progress Tolerance
Type : Floating point number
Range : [0,1]
Default : 1e-12
The optimization will terminate when the relative change in the solution estimate is less than the value of this option for n consecutive iterations, where n is the value of the option Solution Progress Iterations . When using an interior-point algorithm and the barrier parameter is still large, Knitro will first try decreasing the barrier parameter before terminating.
