8.1.6 Splitting Cut-Point Transitions

We consider 2 subproblems corresponding to sets of cut-point transitions as follows.

8.1.6.1 Cut-Point Subproblem 1/2

Here we consider cut-point transition 9.

8.1.6.1.1 Splitting Cut-Point Transitions

There remain no cut-point transition to consider. Hence the cooperation termination is trivial.

8.1.6.2 Cut-Point Subproblem 2/2

Here we consider cut-point transition 16.

8.1.6.2.1 Splitting Cut-Point Transitions

There remain no cut-point transition to consider. Hence the cooperation termination is trivial.
