Keywords: repeated hotstart, max working set recalculations

Hi, I am new to this great package and would like inputs on the following-:

I keep changing my constraint matrix $A$ at every iteration in a loop and resolve the problem. The solution from the previous iteration is expected to be very close to the solution of the current iteration. Is there a way to implement this efficiently in qpOASES ? When I tried to invoke hotstart with the new constraint data, I get an error "ERROR: Maximum number of working set recalculations performed" right when running the loop a third time.

Thanks

No worries, I just had to redefine nWSR variable.

Thanks
