SolverStudio

SolverStudio 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 SolverStudio rather than just read about it. In short: SolverStudio is a free Excel plug-in developed at the University of Auckland that supports optimization and simulation modelling in a spreadsheet using an algebraic modeling language. It is popular in education, the public sector and industry for optimization users because it uses industry-standard modelling languages and is faster than traditional Excel optimisation approaches.

Key takeaways

SolverStudio 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 SolverStudio to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SolverStudio from memory before moving on to harder problems.

Reference excerpt

SolverStudio is a free Excel plug-in developed at the University of Auckland that supports optimization and simulation modelling in a spreadsheet using an algebraic modeling language. It is popular in education, the public sector and industry for optimization users because it uses industry-standard modelling languages and is faster than traditional Excel optimisation approaches. SolverStudio adds a text editor to Excel that is used to create a text-based optimization (or simulation) model using a modelling language such as PuLP, AMPL, GAMS or Julia/JuMP. SolverStudio also provides a tool for naming data on a spreadsheet (and specifying indices for this data), allowing the data to be used in the model. When the model is run, the system automatically reads input data from the spreadsheet and provides it to the model, and then writes the model results back to the spreadsheet. SolverStudio works with a range of commercial and open source modelling systems. By default, it uses PuLP, an open-source Python COIN-OR modelling language. A second open-source Python option is Pyomo which supports non-linear and stochastic programming and provides access to a larger range of solvers. Another supported linear and non-linear modelling option is Julia/JuMP. SolverStudio also makes the two popular commercial modelling languages, AMPL and GAMS available to Excel users. SolverStudio allows models written using these languages to be solved on the user's own PC, or in the cloud using NEOS. The GNU clone of AMPL, GMPL (GNU MathProg Language) is included with SolverStudio. SolverStudio includes the open-source COIN-OR CMPL modelling language, and the Python-based SimPy simulation language. SolverStudio supports general programming using both Python and IronPython, allowing these programming languages to be used to script Excel using the standard VBA interfaces.

Worked examples

Example 1 — a first encounter with SolverStudio

Start with the simplest possible case. Write down what SolverStudio 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 SolverStudio 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 SolverStudio 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 SolverStudio

In research: SolverStudio 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 SolverStudio 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: SolverStudio is common in secondary-school and first-year university syllabi. It links to neighbouring topics Mathematical optimization software, Microsoft Office-related software, University of Auckland, so understanding it makes those chapters shorter.
In everyday life: Look for SolverStudio 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 SolverStudio in simple terms?

Why does SolverStudio 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 SolverStudio?

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.
