Yet most such problems are NP-hard; unless P = NP, there are no efficient algorithms to find optimal solutions. This book shows how to design approximation algorithms: efficient algorithms that find ...

In research area C, we will focus on the development and foundation of mathematical models and their approximations that are relevant in the life sciences, physics, chemistry, and engineering. We will ...

Sometimes it is a good idea to estimate a calculation rather than work it out exactly, if you don’t need to know the exact value. In this situation, round the numbers in the question before ...

The area \(A\) of a square of side length \(s\) is \(A=s^2\text{.}\) Suppose \(s\) increases by an amount \(\Delta s=ds\text{.}\) Draw a square and then illustrate ...

The questions in this quiz are suitable for GCSE maths students studying approximation, rounding to decimal places, rounding to significant figures, truncation, estimating calculations ...

In Archimedes' day, close approximations of pi had been known for over 1,000 years. An Egyptian document dated to 1650 B.C., for example, gives a value of 4 (8/9) 2, or 3.1605. Archimedes' value ...

Sotheby’s Hong Kong is gearing up to stage its first modern and contemporary art auctions in its recently opened premises at Landmark Chater on November 11 & 12. Thaddaeus Ropac welcomes Danish-born ...
