Time complexity is one of the central issues that we will be discussing. What about the number of storage bits needed to implement the above algorithm? Cost to generate all the rows + cost to add them up. What is the number of bit level operations as a function of input? Assume that the input numbers are n bits long. The basic operation for this operation are bit-level operations: adding two 1-bit numbers is considered as a single operation.ġ2 Algorithm for multiplication – school method What is the algorithm for integer addition? Consider binary addition: Given two binary numbers x and y, how long does our algorithm take to add them? We want the answer expressed as a function of the number of input bits.

What Is Computable? Princeton University Press Watch the video:Įarlier we looked at a 2500 old algorithm for multiplying two integers – that assumes that you know how to add two integers, divide an integer by 2 and know to compare two integers.

Quick-sort Dijkstra’s algorithm RSA (for encryption) Fast Fourier Transform Simplex algorithm Huffman coding algorithm, LZW algorithm (both for compression) Hamming code (corrects errors) page-rank algorithm (google) There are probably many other candidates. calculus Applications? Dividing land (after floods) Calculating trajectories of planets architecture (buildings, dams etc.) navigation (finding direction in deep sea) town planning, governance (tax rate, interest etc.)ĩ Famous modern algorithms (20th century algorithms) Intermediate (~ 500 years old) logarithm tables Roots of polynomials, solution of differential equations etc. How old are they?Īn algorithm – more than 3500 years old Rhind Mathematical Papyrus British Museum, London One of the algorithms presented is for multiplying two numbers: _ x x x x x _Ĭlassical (~ 2000 years) Finding area of triangles and other shapes (Heron’s formula) Finding GCD of integers (Euclid’s algorithm) Solving linear system of equations, quadratic equation etc. Algorithms are much older than computers. Another one is in terms of something called Turing machine. What is the exact definition? One way is to create an extremely simple language with only one or two instructions. Intended for human reading, but not machines.

Algorithm is software – without the rigid syntax rules.

You can find the date from the university’s calendar.ĥ What is an algorithm? computer science is often described as a study of algorithms. This will be comprehensive and will take place at the pre-specified time slot. There will be some implementation projects – including a final project for which each (group) will choose a problem from an assigned list. Two mid-semester tests - 30 points (The mid-semester tests will be open-book/notes, and will be in class.) Projects points.

You can discuss the home work problems with others, but you should write up the solution on your own. They are intended to deepen your understanding of the material presented in class and will play a key role in prepare you for the mid-term and final exams. Most home work problems will be from the text. The quiz will be a direct application of the topic being covered.) Home work assignments - 10 points. Short quizzes and class participation – 10 points (There will be a quiz about once a week. Warning: I will assign videos to watch that either covers (roughly) the topic of an upcoming lecture or the background needed for an upcoming lecture.
