The scenario tree aims at approximating a stochastic process combining an ARMA-GARCH ...
WebA scenario is a possible realization of the stochastic variables {1;:::; T}. Hence, the set of scenarios corresponds to the set of leaves of the scenario tree, NT, and nodes of the … 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).
