Isn the KEEL graphical language just another way to create a formula?
It is true that the KEEL graphical language is translated into conventional computer languages for processing, which could possibly be expressed as a textual/numeric formula. However, when the problem is a multi-variable, multi-output, inter-related, non-linear, dynamic system, the development and testing of such a numeric formula (using the common definition of a mathematical formula) would be difficult (very difficult)! Using the KEEL graphical language and the dynamic support built into the KEEL Toolkit, these systems are relatively easy to construct and test. Also, because the KEEL language can be deployed into several different conventional languages, it is easy to build test systems (simulators or emulators) to perform extensive system tests before deploying them in production environments. So the answer is “yes” (formulas are created), but because of the complexity of the formulas, they can best be visualized in the KEEL graphical language. Because another benefit of using KEEL
