Dear All,

I can use MA57 when I run ipopt. However, when I run bonmin,  the ipopt
still used MUMPS.

Bonmin 1.5.2 using Cbc 2.7.6 and Ipopt 3.10.2
bonmin: bonmin.algorithm B-BB
linear_solver "ma57"

This program contains Ipopt, a library for large-scale nonlinear
 Ipopt is released as open source code under the Eclipse Public License
         For more information visit http://projects.coin-or.org/Ipopt

NOTE: You are using Ipopt by default with the MUMPS linear solver.
      Other linear solvers might be more efficient (see Ipopt

              Num      Status      Obj             It       time
NLP0014I             1         OPT 0.010000662        5 0.109

Would you kindly give some light in this matter?

Thanking You,
