As with spreadsheets, visualization software lets an experimenter vary initial conditions or parameters.
Unlike a typical "determinist" forecast, which takes current conditions and simulates a single scenario forward, an ensemble model varies initial conditions slightly and then simulates, propagating uncertainty through the forecast.
Using the Mathematica function Manipulate, it is relatively easy to set up a model with an interface that can quickly vary initial conditions and parameters.
Instead, one may wish to perform many such simulations and vary the initial conditions of each in order to capture the nuanced behavior of the models; such behavior can often be expressed even in a highly reduced set of data (e.g., a density power spectrum).
However, when we varied the initial condition, only the ER model accurately approximated the full deterministic model (Fig. 5 b).
Even when the half-life of a reaction varies with the initial conditions, it is often convenient to quote a half-life, bearing in mind that it applies only to the particular initial conditions.
The individual-level details, such as the exact composition of the neurons in each cluster, vary among different initial conditions and different draws of the random variable ω.
The relative importance of the initial conditions varied with the start of the simulation.
We then calculated the basins of attraction for all attractors at a discrete set of eleven positions corresponding to cycle 13 nuclei in the Bcd-Cad plane with initial conditions varied in Ω = {0 ≤ vHb ≤ 100, vKr = vGt = vKni = 0}.
Also calculations showed that for spin-polarized fuel, there is a driver energy reduction which for maximum gain condition, is less for low initial densities and a gain increase which varies irregularly for different initial conditions.
The initial conditions are varied to take into consideration a large variety of geometrical/mechanical factors, such as the initial front inclination, its height, the initial void ratio, the length of the impacting mass and the inter-particle friction angle.
