Holon paradigm

In MetaCalculus, a holon is an iterative multidimensional calculus process, created dynamically by a template. It is composed of a solution engine as operator and an equations model as operand. The template alphabet contains three operator/operand classes: Optimization, Correlation, and Simulation. This diagram shows three stacked holons in profile, resulting in the nesting of automatic differention.

This diagram is potentially a modeling GUI motif to generate NeoFortran, in which the white boxes are the visible code defining a problem stack, the blue, red, and green boxes are solver engines, and the gray frames highlight differentiation contexts.
