The Square Root valuation (formerly called the Elastic valuation) is similar in concept to the budget valuation, but it bids at a reduced overall cost as the market price rises. In other words, as the market price rises, the Square Root agent asks for less bandwidth than a similarly configured Budget agent.

The two configurable parameters for the Square Root valuation are maximum quantity (“Qty”) and maximum value (“Value”). Set the maximum value to the maximum price you are willing to pay should you receive all of the maximum quantity you specify. Configure the maximum quantity to correspond to the maximum quantity you would like to be allocated. The maximum cost is always half of the number you enter in the Value field, as indicated in the graph to the left of the numerical entry boxes.
