Hans L. Bodlaender is a astronomy 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 Hans L. Bodlaender rather than just read about it. In short: Hans Leo Bodlaender (born April 21, 1960) is a Dutch computer scientist, a professor of computer science at Utrecht University. Bodlaender is known for his work on graph algorithms and parameterized complexity and in particular for algorithms relating to tree decomposition of graphs.

Key takeaways

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

Reference excerpt

Hans Leo Bodlaender (born April 21, 1960) is a Dutch computer scientist, a professor of computer science at Utrecht University. Bodlaender is known for his work on graph algorithms and parameterized complexity and in particular for algorithms relating to tree decomposition of graphs.

Life and work Born in Bennekom, Bodlaender was educated at Utrecht University, earning a doctorate in 1986 under the supervision of Jan van Leeuwen with the thesis Distributed Computing – Structure and Complexity. After postdoctoral research at the Massachusetts Institute of Technology in 1987, he returned to Utrecht as a faculty member. In 1987 he was appointed Assistant Professor and in 2003 Associate Professor. In 2014 he became full professor of algorithms and complexity at Utrecht, and at the same time added a part-time professorship in network algorithms at Eindhoven University of Technology. Bodlaender has written extensively about chess variants and founded the website The Chess Variant Pages in 1995.

Recognition In 2014 he was awarded the Nerode Prize for an outstanding paper in the area of multivariate algorithmics, for his work with Rod Downey, Michael Fellows, and Danny Hermelin on kernelization. A festschrift, Treewidth, Kernels, and Algorithms: Essays Dedicated to Hans L. Bodlaender on the Occasion of His 60th Birthday, was published in 2020.

Worked examples

Example 1 — a first encounter with Hans L. Bodlaender

Start with the simplest possible case. Write down what Hans L. Bodlaender claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Hans L. Bodlaender 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 Hans L. Bodlaender 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 Hans L. Bodlaender

In research: Hans L. Bodlaender appears in astronomy 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 Hans L. Bodlaender 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: Hans L. Bodlaender is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960 births, Academic staff of Utrecht University, Academic staff of the Eindhoven University of Technology, so understanding it makes those chapters shorter.
In everyday life: Look for Hans L. Bodlaender 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.
