1.   All possible pathways are therefore defined by the design of the software.

2.   This could result from bile acid mediated effects on cellular proliferation through several possible pathways as already discussed.

3.   Rather than explore all the possible pathways we need some method of ordering the search.

4.   An isolated particle is not traveling down this pathway or that pathway, but down every possible pathway simultaneously.

5.   Reaching the ends of these fibers, the two photons were forced to make random choices between alternative, equally possible pathways.
