average, every operation within it should be counted
15 times. If, in the other hand, a certain routine is
only executed half the time, it should be counted as
half an execution. To illustrate:
X=X+6
IF(X-77.)1, 2,1
1 Z=X*14.
GO TO 3
2 Z=X*16./W
3 CONTINUE
If you assume extended precision, and a proba-
bility of one-third for path 1 and two-thirds for
path 2, the estimated execution time is
