Intermediate solutions in binary programming

I am running a binary program using the matlab command intlinprog but it takes a long time to compute. I want to stop the command in middle of operation and extract some intermediate optimal value. In the command window, it is stated clearly that 10.000 nodes are explored, then after sometime it says 20,000 nodes are explored, and so on. I don't want to wait till a lot of nodes are explored. Is there any way to study the intermediate optimal solution, after only 20,000 nods have been expandeed?

Set the MaxNodes option parameter to 20000.

You might be interested in using an output function to report intermediate results. See intlinprog Output Functions and Plot Functions.
