global.deterministic

Syntax

b = global.deterministic

global.deterministic = b

Get/set deterministic mode. In deterministic mode, all model runs starting with identical initial conditions result in identical solutions at the cost of a > 20% reduction in performance. In nondeterministic mode, on the other hand, identical initial conditions may lead to divergent solutions. The divergence is due only to the order of summation, and all solutions are equally valid to machine precision.

Returns:

b - deterministic status

Accepts:

b - deterministic status
