Summary0000478: conopt solver varying the wrong variables
Descriptionneed some way of specifying which FREE variables are to be varied. for cycle optimisation, it's too difficult to converge a solution otherwise, we see wild variations in variations which with QRSlv had been directly solved using precendence ordering of equations.

I think that this comment instead be pointing towards a need for a reduced-space SQP solver, or some other kind of optimisation process for ASCEND. Needs discussion.
