WebJan 1, 2012 · 4.4.1 Regression Models. One way to set up a scenario tree is to define properties you want to be present in the tree, and then, for example, by non-linear programming, create a tree with those properties. In such a problem, the variables are the outcomes of the random variables and possibly also the probabilities. WebOct 10, 2024 · For example, a game map could have predefined positions for trees. But these trees could be dynamic in that the player can cut them, and there is a system that will make new ones grow. An example of "constantly changing" dynamic content could be if the trees spread (new trees spawn and grow near where other trees exist).
