TOMLAB

TOMLAB is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand TOMLAB rather than just read about it. In short: The TOMLAB Optimization Environment is a modeling platform for solving applied optimization problems in MATLAB. Description TOMLAB is a general purpose development and modeling environment in MATLAB for research, teaching and practical solution of optimization problems.

Key takeaways

TOMLAB belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect TOMLAB to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of TOMLAB from memory before moving on to harder problems.

Reference excerpt

The TOMLAB Optimization Environment is a modeling platform for solving applied optimization problems in MATLAB.

Description TOMLAB is a general purpose development and modeling environment in MATLAB for research, teaching and practical solution of optimization problems. It enables a wider range of problems to be solved in MATLAB and provides many additional solvers.

Optimization problems supported TOMLAB handles a wide range of problem types, among them: Linear programming Quadratic programming Nonlinear programming Mixed-integer programming Mixed-integer quadratic programming with or without convex quadratic constraints Mixed-integer nonlinear programming Linear and nonlinear least squares with L1, L2 and infinity norm Exponential data fitting Global optimization Semi-definite programming problem with bilinear matrix inequalities Constrained goal attainment Geometric programming Genetic programming Costly or expensive black-box global optimization Nonlinear complementarity problems

Additional features TOMLAB supports more areas than general optimization, for example: Optimal control with PROPT using Gauss and Chebyshev collocation. Automatic differentiation with MAD Interface to AMPL

Further details TOMLAB supports solvers like CPLEX, SNOPT, KNITRO and MIDACO. Each such solver can be called to solve one single model formulation. The supported solvers are appropriate for many problems, including linear programming, integer programming, and global optimization. An interface to AMPL makes it possible to formulate the problem in an algebraic format. The MATLAB Compiler enables the user to build stand-alone solutions. Sister products are available for LabVIEW and Microsoft .NET. Modeling is mainly facilitated by the TomSym class.

Worked examples

Example 1 — a first encounter with TOMLAB

Start with the simplest possible case. Write down what TOMLAB claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to TOMLAB before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about TOMLAB ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of TOMLAB

In research: TOMLAB appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses TOMLAB in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: TOMLAB is common in secondary-school and first-year university syllabi. It links to neighbouring topics Mathematical optimization software, Numerical software, so understanding it makes those chapters shorter.
In everyday life: Look for TOMLAB outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is TOMLAB in simple terms?

The TOMLAB Optimization Environment is a modeling platform for solving applied optimization problems in MATLAB. Description TOMLAB is a general purpose development and modeling environment in MATLAB for research, teaching and practical solution of optimization problems.

Why does TOMLAB matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study TOMLAB?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
