Re88: The multimap Function, Part B
(Best-First-Search Part 7, AIMA4e pp. 73-74)

Finishing what we started with multimap.
Using verbose printing to watch the behavior of multimap; demonstrating the side-effects behavior of executing Map, which calls multimapand passes a modified tlinksto it; but it's not clear why the Map-modified tlinkswould be the same object as the global tlinks.

tmapinstantiating Mapand causing a global change in tlinksby passing a (correctly) modified version out of itself to multimap. We are 90% sure this is what's happening. But it is confusing. Shouldn't the tlinksobject passed out of Mapbe in a different namespace or something?
