An ordinary hill is the visualization of strong causality. In the mathematical abstraction this is continuity. The theory of the Evolution-Strategy derives the central law of progress as the leading idea for optimization.
Similar causes have similar effects.
The classical definition that equal causes have equal effects is now referred to as weak causality, because it is so unrealistic. Sufficient strong causality is the norm for all human action. Thank Heaven that a slight turn of a steering weel has a small effect. .
