For Operator 2 you have the following options (assuming that the algorithm is chosen to be “Double”): • Sum • Product • Maximum • Minimum • Minus • Divide • Greater than • Not less than • Less than • Not grt. than • Equal to • Not equal to In the following we denote by G the combined value of the global input values, i.e., the result of Operator 1. Moreover, L denotes the local factor of the node, and R denotes a random number generated from the distribution of the node. If the node does not include stochastic values, the R factor is of course skipped. Sum If “Operator 2” is “Sum”, then the output value of the node is calculated by using the following rule: Output value = G + (L · R) Product If “Operator 2” is “Product”, then the output value of the node is calculated by using the following rule: Output value = G · (L · R) Maximum If “Operator 2” is “Maximum”, then the output value of the node is calculated by using the following rule: Output value = Max(G, (L · R)) Minimum If “Operator 2” is “Minimum”, then the output value of the node is calculated by using the following rule: Output value = Min(G, (L · R)) Minus If “Operator 2” is “Minus”, then the output value of the node is calculated by using the following rule: Output value = G - (L · R) Divide If “Operator 2” is “Divide”, then the output value of the node is calculated by using the following rule: Output value = G / (L · R) Note that if L · R = 0, the output value is simply defined to be zero. Greater than If “Operator 2” is “Greater than”, then the output value of the node is calculated by using the following rule: Output value = 1 if G > (L · R) and zero otherwise. Not less than If “Operator 2” is “Not less than”, then the output value of the node is calculated by using the following rule: Output value = 1 if G ≥ (L · R) and zero otherwise. Less than If “Operator 2” is “Less than”, then the output value of the node is calculated by using the following rule: Output value = 1 if G < (L · R) and zero otherwise. Not grt. than If “Operator 2” is “Not grt. than”, then the output value of the node is calculated by using the following rule: Output value = 1 if G ≤ (L · R) and zero otherwise. Equal to If “Operator 2” is “Equal to”, then the output value of the node is calculated by using the following rule: Output value = 1 if G = (L · R) and zero otherwise. Not equal to If “Operator 2” is “Not equal to”, then the output value of the node is calculated by using the following rule: Output value = 1 if G ≠ (L · R) and zero otherwise.
