what is the results including a plateau is more economical than including a step, which is more economical than including a combination of a step and plateau. Furthermore, the inclusion of up to four plateaus is more economical than the inclusion of one step or any combination of steps and plateaus. The same trend is also apparent for the MID normalized functions, with the exception that for this parameter the use of four plateaus is less economical than the use of one step. With the inclusion of three steps and all subsequent combinations of function type, the mean search cost using the QRange becomes increasingly sensitive until it becomes more economical to use the MID than the QRange when the function type with four steps is implemented. The most economical search value produced from all 285 function types was that of bare function using the QRange normalization parameter, requiring on average a search of only 11% of the total designated search to find the home location
