The bid-rent curve has a negative slope because the activities balance the bid-rent with the cost of transportation to the point of attraction. Farther distances require greater transportation cost and thus reduce the amount of rent that can be paid. The bid-rent curve indicates why rents, and by inference land values, tend to be higher near central locations. Â« Better Business Bureau | big business Â».

Recursion in computer programming is exemplified when a function is defined in terms of simpler, often smaller versions of itself. The solution to the problem is then devised by combining the solutions obtained from the simpler versions of the problem.
Recursion means defining a problem in terms of itself. This can be a very powerful tool in writing algorithms. Recursion comes directly from Mathematics, where there are many examples of expressions written in terms of themselves. For example, the Fibonacci sequence is defined as: F(i) = F(i-1) + F(i-2) Recursion is the process of defining a problem (or the solution to a problem) in terms of (a simpler version of) itself. For example, we can define the operation find your way home as: If you are at home, stop moving. Take one step toward home.
