I have a question regarding branching in CPLEX solver. Is there any way to display on which variable the algorithm used as the branching variable ?

I am working on a Branch-and-Bound problem with the CPLEX solver and below is the CPLEX.opt that I used so far:

Code: Select all

```
$onecho > cplex.opt
mipdisplay 5
mipinterval 1
simdisplay 2
cutsfactor 0
preind 0
divetype 1
nodesel 0
lpmethod 1
heurfreq -1
miptrace tree.txt
$offecho
test.OptFile = 1;
```

Thank you in advance,

Kevin
