No, the status of the optimization is only in C code until the finish.

Whyever would a partially run optimization be useful?  You can arrange for 
your optimizand to record the latest set of parameters if you wish, and 
then just interrupt R in the usual way.  Or you can set a limit on the 
number of iterations.
