Figure 5
The relationship between R F and R I for varying levels of F. Legend: F (feasibility) of 10%, 50% 75% and 90% shown from light to dark. Line in black shows ratio of one, R F = R I , representing a scenario in which all nets are found R I is the break even ratio under ideal conditions and R F is the break even ratio when feasibility is considered. Arrows represent the relationship between an R I and R F when R I = 1.6 and F = 0.75.
