The FC Compiler Guide: Mathematical Modeling with Fortran Calculus focuses on utilizing a specialized Calculus-level compiler (FC-Compiler™) designed to minimize programming overhead by allowing engineers and scientists to solve mathematical models directly from mathematical statements. Developed by Joe Thames and Optimal Designs Enterprise, this tool focuses heavily on Automatic Differentiation (AD) to automate optimization and parameter tuning. Core Concept: Calculus-Level Programming
Standard programming languages require you to write complex loops and manual numerical methods (like Runge-Kutta or Newton-Raphson) to approximate derivatives and integrals.
The FC-Compiler introduces a MetaCalculus paradigm. Instead of coding the numerical solver, you only supply: The core mathematical equations. The problem’s constraints.
The objective function (the target you want to maximize or minimize).
The compiler handles the underlying mathematical operations automatically, decoupling the mathematical model from the algorithm. Key Features of Fortran Calculus (FC)
Automatic Differentiation (AD): FC mathematically computes exact derivatives internally using AD. This eliminates the truncation errors found in standard numerical differentiation.
Implicit Problem Solving: It is heavily optimized for “inverse problems,” parameter optimization, and data-fitting, where the ideal variables must be back-calculated from a desired output.
The FIND Statement: The guide details how simulation code can be immediately converted into optimization code using a unique FIND syntax to tweak parameters automatically during the execution of differential equations.
Drastic Code Reduction: According to developer documentation, transitioning a standard engineering model to FC can reduce the required code by up to 90%. Historical Origins
The language and compiler logic trace their roots back to NASA’s Apollo Space Program. TRW developed the earliest versions of calculus-level compilers to handle the extreme orbital mechanics and trajectory optimizations required to navigate to the moon. Over the subsequent decades, these concepts were commercialized and bundled into the modern Windows-compatible FC-Compiler. Educational and Industry Resources
Example Demos: The software ecosystem includes over 50 reference models addressing algebraic equations, Ordinary Differential Equations (ODEs), and Partial Differential Equations (PDEs).
The Textbook Companion: The guide is often paired with textbooks authored by Phil Brubaker and Joe Thames, accessible via Goal-Driven Textbooks. These resources provide half a century of real-world industry problems translated into calculus-level solutions.
