I have other questions:
1. when I draw the grid graph and want to use the kruskal to mimic the spanning
tree, I got the animation control, and I do not know what is the use of
Backup, Break, Clear Breaks.
2. in Graph-View, there is option called refresh graph, what is for?
3. here I onlu use the interactive mode to write STk, can I write the
file, then compile it, just like lisp(load "file nema
", then compile-file..).
thanks, I appreciate!
