Optimal world scenario

Horvitz 1989, Hairston Dillon 1990) are important sources of genetic variation. This sort of variation would be expected to increase genetic correlations, in contrast to the optimal-world case. Some believe that laboratory studies of field-evolved populations are therefore biased toward rejecting the optimal-world scenario and are not relevant to the question (Service Rose 1985). 

A new set of data has now to be included in each model instance the initial inventory of each tank and its current state. The initial state is crucial either in the model performance as well as on the optimal resources allocation. In a real world scenario, this data is provided by the prior time horizon. 

In summary, there is good evidence that both optimal-world and cruel-world scenarios supply variation in fitness components, but the quantitative balance between the two is unclear. 

Till here, we assumed deterministic demands. However in real world scenarios, it is highly likely that demand changes fitting a statistical distribution. Newsboy model is a widely used approach. We can assume the demand D as a random variable. A boy purchases Q newspapers to sell and based on the demand, he has an underage cost c (when demand is more than the number of newspapers, 0 or overage cost Co (when Q is greater than the demand). Then the optimal number of newspapers to purchase is found by ... 

The unit cost heuristic stops since the number of periods is reached. The lot size for the fifth period to span two periods is 65 + 44 = 109. The lot sizes are the same with Silver-Meal results. However, it is most likely that two heuristics will result in different lot sizes solving bigger real world problems. Heuristics are not guaranteed to find optimal solutions. Also, it is hard to judge which heuristic is better for all scenarios.
