hi，everyone：

I encountered a problem，When I use oplrun-v .mod .dat, the calculation time of the same model is very different. The first calculation of 200s, the second 700s, the third 2000s has not stopped. Why is that？

And oplrun-v followed by those numbers What does it mean? For example 7000 28 34 F?

! Time = 55.10s, Explored branches = 294,179, Memory usage = 985.0 MB
 !          Best Branches  Non-fixed    W       Branch decision
   718,642,191.283    7,000         28   34         0  = Yji1#17#12
   718,642,191.283    7,003          3   35         1  = Yji1#4#0
   718,642,191.283    7,000         18   36         0  = Yji1#15#13
   718,642,191.283    7,007        190   37   F     1  = Yji1#13#6
   718,642,191.283    7,000        109   38         0  = Yji1#11#5
   718,642,191.283    7,000         99   39         0  = Yji1#9#3

Hi

option -v      means            verbose
