Maros and Meszaros Convex QP Test Problems (MAT Format)

Problem format:

  min   0.5 x'Qx + c'x 
  s.t.  rl <= Ax <= ru,
        lb <=  x <= ub.

Notes

  • If rl = ru, setting b = rl, we can get
    min  0.5 x'Qx + c'x
    s.t. Ax = b 				
         lb <= x <= ub.

These problems are consistent with the discrption from Maros and Meszaros.

  • In the discription about these test problems from Maros and Meszaros, they assume rl=ru. BUT we do observe that for quite a few problems, rl ~= ru. For details of extracted problems, see log.txt.

  • To regenerate the mat files, run setup first and then qps2mat. The function coinRead only runs on Windows system!!
