Hideo Fujiwara

Hideo Fujiwara 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 Hideo Fujiwara rather than just read about it. In short: Hideo Fujiwara (藤原秀雄, Fujiwara Hideo) is a Japanese computer scientist who made significant contributions to ATPG (automatic test pattern generation) algorithms. As one of his works, he invented the FAN algorithm in 1983, which was the fastest ATPG algorithm at that time, and was adopted by industry.

Key takeaways

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

Reference excerpt

Hideo Fujiwara (藤原秀雄, Fujiwara Hideo) is a Japanese computer scientist who made significant contributions to ATPG (automatic test pattern generation) algorithms. As one of his works, he invented the FAN algorithm in 1983, which was the fastest ATPG algorithm at that time, and was adopted by industry. He was born in Nara, Japan, and studied electronic engineering at Osaka University, where he received his B.E. degree in 1969, M.E. in 1971, and Ph.D. in 1974. He was with Osaka University from 1974 to 1985, Meiji University from 1985 to 1993, Nara Institute of Science and Technology (NAIST) from 1993 to 2011, and Osaka Gakuin University from 2011 to 2021. Presently, he is Professor Emeritus of NAIST.

Worked examples

Example 1 — a first encounter with Hideo Fujiwara

Start with the simplest possible case. Write down what Hideo Fujiwara 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 Hideo Fujiwara 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 Hideo Fujiwara 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 Hideo Fujiwara

In research: Hideo Fujiwara 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 Hideo Fujiwara 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: Hideo Fujiwara is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1946 births, Academic staff of Nara Institute of Science and Technology, Computer scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Hideo Fujiwara 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.
