Computing Total &Free Slack in the Basic Formulation
Task	LS-ES= Total Slack	(Min ES's of successors)-EF= Free Slack	Task	LS-ES= Total Slack	(Min ES's of successors)-EF= Free Slack
A	2-0=2	min {10, 10} - 10 = 0	I	26 - 19 = 7	24 - 24 = 0
B	0-0=0	min {19, 19, 19, 19} - 19	J	26 - 24 = 2	28 - 28 = 0
C	18-0=18	24 - 13 = 11	K	23 - 23 = 0	29 - 29 = 0
D	22 - 10 = 12	28 - 18 = 10	L	30 - 28 = 2	38 - 36 = 2
E	12 - 10 = 2	24 - 24 = 0	M	29 - 29 = 0	38 - 38 = 0
F	19 - 19 = 0	"min {24,23} - 23"	N	31 - 24 = 7	38 - 31 = 7
G	22 - 19 = 3	"min {24,23} - 20"
H	20 - 19 = 1	23 - 22 = 1
