Event generation refers to the computer-based simulation of events, usually using the Monte Carlo method and an event generator.
Choice of event weight normalisation
There are basically four different choices to normalise event weights. Choosing a notation where 
denotes the weight of the 
th event, 
is the number of generated events, 
is the generated cross section value and 
denotes the average, the different conventions are[1]:
-
meaning that 
-
meaning that 
-
meaning that 
-
meaning that 
The sums are over all generated events.
