Realistically speaking its important to have a margin of safety. Solutions can also be generated by cloning an existing solution which is analogous to asexual reproduction. 20000 010 Hybrid Vehicle Vehicle Purchase Cost Vehicle Operating Cost per Mile Useful Life of Vehicle Miles per Year Miles per Gallon Average Fuel Price per Gallon 18000 013 15 years 16500 31 368 Alternative Vehicle Vehicle Purchase Cost Vehicle Operating.

The crossover point is normally illustrated in a chart where average costs are plotted against student numbers as can be seen in Figure 2e. It is one way to stochastically generate new solutions from an existing population and is analogous to the crossover that happens during sexual reproduction in biology. At this crossover point a term coined by Joe Dominguez and Vicki Robin in Your Money or Your Life your investment returns provide more money than you spend. Realistically speaking its important to have a margin of safety.
