_sequence of actions vs sequence of snapshots.

"one of the first important paradigm shifts that programmers struggle to make is from viewing an algorithm as a sequence of actions to viewing it as a sequence of snapshots of the state of the computer." jeff edmonds , How to think about algorithms

Personally I think the latter is particularly useful in "design computing" , when the result desired is not known in exactitude . Once the snapshots are somewhat outlined, we can proceed to flesh out the design algorithm with operations to get from one state to another....

This inclination betrays a huge persnoal reliance on being able to use modelling techniques to "think-through" an algorithm .. i.e get from one state to another..
