A New Method for Finding Constant Terms in the Context of Gene Expression Programming*
نویسندگان
چکیده
Most of the potential function expressions subjected to function finding contain constant terms. Gene Expression Programming (GEP)’s effectiveness of function finding has been severely limited due to a lack of constant creating ability. Though this issue has been realized and discussed by many GEP researchers, an efficient method has never been established. This paper presents a new method to find functions with constant terms in the context of GEP. Experiments show its performance is outstanding: for simple integer constant terms, it surpasses original GEP up to 1-2 orders of magnitude in terms of efficiency, and for fractional constant terms, it provides an exclusive solution which no existing methods could ever achieve.

Presenting a new equation for estimation of daily coefficient of evaporation pan using Gene Expression Programming and comparing it with experimental methods (Case Study: Birjand Plain)
One of the most important componenets of water management in farms is estimating crops’ exact amount of evapotranspiration (water need). The FAO-Penman-Montheis (FPM) method is a standard method to evaluate other techniques which are used for easy calculation of potential evapotranspiration, when lysimeter datasheets are not available. This study was carried out based on 18 years’ climatic dat...
