A key example of an optimal stopping problem is the secretary problem. Optimal stopping problems can often be written in the form of a Bellman equation , and are therefore often solved using dynamic programming .
If the capacity left is less than this limit demand for class 2 is rejected. If a continuous distribution F j ( x ) {\displaystyle F_{j}(x)} is used to model the demand, then y 1 ⋆ {\displaystyle y_{1}^{\star }} can be calculated using what is called Littlewood’s rule :
For example, when a securities firm is holding a customer limit order (an instruction to buy or sell securities at a certain price), the firm cannot ignore that order and cannot trade for their account using a price that would satisfy the customer's limit order without executing the customer limit order. The rule is applicable both in normal ...

Mis-perceptions of feedback and time delays. In 1979, Buffa and Miller highlighted that in their example. If a retailer sees a permanent drop of 10% of the demand on day 1, he will not place a new order until day 10. That way, the wholesaler is going to notice the 10% drop at day 10 and will place his order on day 20.
