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.
How recursion increases efficiency Recursion is a type of divide-and-conquer technique used to solve difficult programming problems by reducing a problem to simpler, but identical, sub-problems. The sub-problems are then reduced to sub-sub-problems. This multi-step reduction process continues until a trivial case is reached.
