Hi Zhanibev,

That's rather normal and due to the warm starting capability of the dual
simplex. The more variables you fix, the less iterations you need to
re-optimize, as a rule of thumb.
Also, the further you proceed in your optimization process, the deeper in
the tree you operate (partially indicated by the increasing mdpt).
Both together gives the described effect.

Actually, few iterations per node is a good thing: it makes your solution
process fast.

What would worry me, if I was you, is that hardly any pruning happens.
After 20000 explored nodes, you are left with 19525 open nodes. This means
that you are nearly spanning up a complete tree so far.
At least the dual bound increases, so there is some hope that things get
better once you find a good primal solution.

Best from Berlin,
Timo
