Depending on the chosen algorithm for a node, its output value will be calculated by using either one or two operators, or none at all. In particular, the first operator, called 窶廾perator 1窶 is used when the algorithm is either 窶廨lobal only窶, 窶彜ingle窶 or 窶廛ouble窶.
If the algorithm is either 窶廨lobal only窶 or 窶廛ouble窶, Operator 1 describes how to combine the global input values. If the algorithm is 窶彜ingle窶, Operator 1 describes how to combine the global input values as well as the local value.
The second operator, called 窶廾perator 2窶 is used only when the algorithm is 窶廛ouble窶. In this case it is used to describe how to combine the result from Operator 1 and the local value.
Note that unless the algorithm is 窶廰ocal only窶 or 窶廚orrelation窶, you can see which Operator 1 is being used in a given node by looking at its icon.
For Operator 1 you have the following options:
窶｢ Sum
窶｢ Product
窶｢ Maximum
窶｢ Minimum
Sum
If 窶廾perator 1窶 is 窶彜um窶, then the node combines all input values by adding them. If the chosen algorithm is 窶彜ingle窶, the node also includes its own local value in the sum.
Product
If 窶廾perator 1窶 is 窶弃roduct窶, then the node combines all input values by multiplying them. If the chosen algorithm is 窶彜ingle窶, the node also includes its own local value in the product.
Maximum
If 窶廾perator 1窶 is 窶廴aximum窶, then the node combines all input values by taking the maximum value. If the chosen algorithm is 窶彜ingle窶, the node also includes its own local value in the maximum.
Minimum
If 窶廾perator 1窶 is 窶廴inimum窶, then the node combines all input values by taking the minimum value. If the chosen algorithm is 窶彜ingle窶, the node also includes its own local value in the minimum.
