Some services offered by Chegg have been repeatedly documented as being problematic. [49] These services include "homework help" where "Chegg experts" solve homework questions for students. [50] Academic file-sharing [51] [52] also occurs in the form of students posting homework question sheets soliciting answers.
Chegg Tutors was founded in 2011 as InstaEDU and launched into public beta in May 2012. At that time, the company also announced that it had raised $1.1M in venture capital funding from The Social+Capital Partnership. [2] Two of the company's co-founders had previously run an in-home tutoring company called Cardinal Scholars.
Chegg stock has lost nearly 70% over the last year and has been roughly cut in half in 2024. From its peak in 2021, the stock is down over 95%. Since the launch of ChatGPT in late 2022 the company ...
How to Solve It suggests the following steps when solving a mathematical problem: . First, you have to understand the problem. [2]After understanding, make a plan. [3]Carry out the plan.
Modifying the condition in this way can make a problem either harder or easier to solve (intuitively, it is harder to justify a positive answer but might be easier to justify a negative one). Kurtz and Simon [ 34 ] proved that the universally quantified problem is, in fact, undecidable and even higher in the arithmetical hierarchy ...
The divide-and-conquer paradigm is often used to find an optimal solution of a problem. Its basic idea is to decompose a given problem into two or more similar, but simpler, subproblems, to solve them in turn, and to compose their solutions to solve the given problem. Problems of sufficient simplicity are solved directly.
A solving algorithm for UNAMBIGUOUS-SAT is allowed to exhibit any behavior, including endless looping, on a formula having several satisfying assignments. Although this problem seems easier, Valiant and Vazirani have shown [ 25 ] that if there is a practical (i.e. randomized polynomial-time ) algorithm to solve it, then all problems in NP can ...
A method for solving a decision problem, given in the form of an algorithm, is called a decision procedure for that problem. A decision procedure for the decision problem "given two numbers x and y, does x evenly divide y?" would give the steps for determining whether x evenly divides y. One such algorithm is long division. If the remainder is ...
