Omer Reingold

Omer Reingold 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 Omer Reingold rather than just read about it. In short: Omer Reingold (Hebrew: עומר ריינגולד) is an Israeli computer scientist. He is the Rajeev Motwani professor of computer science in the Computer Science Department at Stanford University and the director of the Simons Collaboration on the Theory of Algorithmic Fairness.

Key takeaways

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

Reference excerpt

Omer Reingold (Hebrew: עומר ריינגולד) is an Israeli computer scientist. He is the Rajeev Motwani professor of computer science in the Computer Science Department at Stanford University and the director of the Simons Collaboration on the Theory of Algorithmic Fairness. He received a PhD in computer science at Weizmann in 1998 under Moni Naor. He received the 2005 Grace Murray Hopper Award for his work in finding a deterministic logarithmic-space algorithm for st-connectivity in undirected graphs. He, along with Avi Wigderson and Salil Vadhan, won the Gödel Prize (2009) for their work on the zig-zag product. He became a Fellow of the Association for Computing Machinery in 2014 "For contributions to the study of pseudorandomness, derandomization, and cryptography."

Worked examples

Example 1 — a first encounter with Omer Reingold

Start with the simplest possible case. Write down what Omer Reingold 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 Omer Reingold 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 Omer Reingold 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 Omer Reingold

In research: Omer Reingold 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 Omer Reingold 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: Omer Reingold is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of Weizmann Institute of Science, Computer scientist stubs, Fellows of the Association for Computing Machinery, so understanding it makes those chapters shorter.
In everyday life: Look for Omer Reingold 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.
