Single This algorithm is used for nodes where the local value is combined with the global input values using a single operator. The output value of a node with “Single” as algorithm is computed according to the following rule: Output value = Op1(X1, X2,…, LR) where Op1 is the “Operator 1” for this node, X1, X2,… represent its input values, L is the local factor of the node, and R is a random number generated from the distribution of the node. Note, however, that if the node does not include stochastic values, the R-factor is skipped. Whenever you create a stochastic node which is not “Independent”, its algorithm is initialized to be “Single”.
