В теле программы стратегия поведения рационально-шумовых агентов описана следующим образом:
public class RationalStrategy implements Strategy {
private static final RationalStrategy INSTANCE = new RationalStrategy();
public static RationalStrategy getInstance() {
return INSTANCE;
}
private RationalStrategy() {
}
public double getPrice(Trader trader, Regulator regulator, int v) {
