Second solve in Proc Optmodel with different starting point (init)

[ODENWALD]

After a first    solve with  NLP  with  ms-feature  I wanted to place a second solve with logic

x.init  =  x.msinit  etc  for all variables  and  solve  ..... .

That's not allowed.

Who knows how to implement it ?

The .INIT suffix is deprecated, but you can do the following to set all variables in one loop:

   for {j in 1.._NVAR_} _VAR_[j] = _VAR_[j].msinit;

Thanks, Rob .

.... so easy, but I was looking the wrong direction.  Using the  ms  feature   .msinit   is clearly more important. But why had you decided to deprecate  .init  ?

The .INIT suffix was confusing (especially because it was not populated by the INIT option in the VAR statement) and not very useful, so we removed it as of SAS/OR 13.2.  To supply initial values to be used by the NLP solver, just assign those values to the variables as I showed.
