What are Math Optimization Problems?

Finding the optimal objective value for a math model.

Mathematically speaking an Optimization problem consists of one's equations plus an objective function. A solver will tweak all available parameters in a program until the solver finds an optimal objective value. Quick and accurate solutions. Try solving your problem in an Optimization setting. Its great!

Calculus-level programming solves Optimization Problems

If a solution exists, Calculus programming can find it. Say your math model is y = f(x; a, b, c) and you want to find your parameters a, b, & c that maximize Y at X=3. Calculus programming has a find statement that handles this quite nicely. A few runs should convince you on the solution or that your math model needs improving.

Calculus programming allows nesting of Optimization problems.

Optimization Examples:

Problem-Solving Applications include:

CurvFit: a curve fitting program with Lorentzian, Sine, Exponential and Power series are available models to match your data.

Match-n-Freq: a Matched Filter program used to filter signals and slim pulses.

Industry Problem-Solving Descriptions include:

Business Strategies & War Gaming: Buy, Sell, Hold options may be tested for an entire company, individual plant(s), or whole product lines. Imagine an increase in control settings from a 1 or 2 digits (i.e., a guess value) to an 8+ digit accuracy resulting from a Calculus programming calculation!

Pulse Slimming to minimize InterSymbol Interference: via Arbitrary Equalization with Simple LC Structures to reduce errors.

Voice Coil Motor: basically an electromagnetic transducer in which a coil placed in a magnetic pole gap experiences a force proportional to the current passing through the coil.

Electrical Filter Design: find the transfer function's poles & zeros; H(s) = Yout(s) / Yin(s).

Digitized Signal from Magnetic Recording: Magnetic recording of transitions written onto a computer disc drive may produce an isolated pulse as shown.

AC Motor Design: a simulation program for A.C. motor design that was reapplied as a constrained optimization problem with 12 unknown parameters and 7 constraints.

PharmacoKinetics: an open-two- compartment model with first order absorption into elimination from central compartment is presented here.
