What Does Deterministic Algorithm Mean?
A deterministic algorithm is an algorithm that is purely determined by its inputs, where no randomness is involved in the model. Deterministic algorithms will always come up with the same result given the same inputs.

By contrast, probabilistic models include an element of probability. One way to think about probabilistic and deterministic models is to think about linear programming, where in earlier traditional paradigms, results were purely deterministic.
