Stochastic Replace Samples

Units:Yes/No
Default Value:False (0)
Validation Rule:False (0) or True (-1)
Description:If the full branch samples in rolling horizon or the forward pass samples in SDDP should be replaced by user-defined samples

Stochastic Replace Samples is an advanced option for the Rolling Horizon or SDDP algorithm.

When enabled, the full branch samples in rolling horizon or the forward pass samples in SDDP generated for the scenario tree are replaced with user-defined samples. These user-defined samples are provided as Variable objects with names that match the original Variable object's providing the inflow samples but with "_FWD" appended to the name. For example, if you have Storage Natural Inflow defined with a Variable called "Big Lake" then the corresponding forward pass samples would be defined by a Variable named "Big Lake_FWD". That Variable should have Sampling Method = "User" and the Profile band count should match the number of full branches (Global Tree Stages Leaves).
