[Scip] Cutoff node being solved again?

[何河]

Hi there,

Based on some heuristics, I called SCIPcutoffNode after a node was
selected. However I found it was solved again soon. For example, the debug
message shows:

[src/scip/solve.c:3593] debug: Processing node 1 in depth 0, 0 siblings
[src/scip/solve.c:4508] debug: Processing of node 1 in depth 0 finished. 0
siblings, 2 children, 0 leaves left
[src/scip/solve.c:3593] debug: Processing node 2 in depth 1, 0 siblings
[src/scip/solve.c:4508] debug: Processing of node 2 in depth 1 finished. 0
siblings, 2 children, 0 leaves left
[src/scip/solve.c:3593] debug: Processing node 3 in depth 2, 0 siblings
[src/scip/solve.c:4508] debug: Processing of node 3 in depth 2 finished. 0
siblings, 0 children, 0 leaves left
[src/scip/solve.c:3593] debug: Processing node 1 in depth 0, 0 siblings
[src/scip/solve.c:4508] debug: Processing of node 1 in depth 0 finished. 0

[src/scip/solve.c:3593] debug: Processing node 2 in depth 1, 0 siblings
[src/scip/solve.c:4508] debug: Processing of node 2 in depth 1 finished. 0
siblings, 2 children, 0 leaves left
[src/scip/solve.c:3593] debug: Processing node 3 in depth 2, 0 siblings
[src/scip/solve.c:4508] debug: Processing of node 3 in depth 2 finished. 0
siblings, 2 children, 0 leaves left

The log I got doesn't seem to indicate there's a restart.. Why node 1, 2, 3
is solved repeatedly? Thank you very much!!
