Fix non-determinism in running examples test

[vazirim]

Is your feature request related to a problem? Please describe.

Currently we have a test that runs all the examples and evaluates their output wrt known stored output. We can reset the outputs by setting this variable to True.

A few examples have been excluded because of non-determinism.

Describe the solution you'd like

Figure out a way of running and testing the non-deterministic examples by storing multiple results for each. Identify sources of non-determinism in these examples and mitigate if possible.
