Hello everyone, I am using -p gp.tree.print-style=latex  that I learned from ecj tutorial#4 to print some results into my paper.

After including the packages, a sample result looks like in screenshot, and screenshot2.

The code for screenshot is:






Obviously there is a huge white space I don't want, so i deleted \begin{center} and \end{center} to see what happens. Then I get screenshot2, which is not an improvement at all.

What is the correct way to print this out? Thanks!
