/**
 * After receiving the results of the auction, every land holder updates his
 * profit motive barometer. This plan is used by all land holders who have low
 * profit motivation.
 * 
 * In this plan, it is not considered whether the land holder has participated
 * or successful in the auction. Instead, he checks whether at least one person
 * has gained any profit by winning the auction. The land holder does not bother
 * about the amount of profit. If somebody has gained any profit, he slightly
 * increase his profit motive barometer. The factor
 * ConservationUtils.increaseFactorForPWhenLowP is used to increase land
 * holder's profit motive barometer.
