The following online expert system is the output of an explorative modelling approach aiming an additive calculation of yield
based on real experiences about observed objects (e.g. experimental units, fields, enterprises, regions, counties, countries).
The partial combinatorial space itself makes possible (involving multilayered and consistency-oriented similarity analyses)
the estimation of stair-levels of input-variables according to their impact volumes as a part of the analysed yield.
The expert system is parallel a simulation system: it delivers estimation both of genetic potential and for each classified combination of input sources.
