What is the hardest math problem in history?

Poincaré Conjecture

What is the biggest math problem in the world?

Riemann Hypothesis of 1859

What is the easiest math problem in the world?

If by ‘simplest’ you mean easiest to explain, then it’s arguably the so-called ‘Twin Prime Conjecture’. Even schoolchildren can understand it, but proving it has so far defeated the world’s best mathematicians. Prime numbers are the building blocks from which every whole number can be made.

What is the hardest equation?

It’s called a Diophantine Equation, and it’s sometimes known as the “summing of three cubes”: Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100. On the surface, it seems easy.

What is the highest level of math?

Calculus

Which is harder Calc 1 or 2?

Answers and Replies. calc 2 is just as easy as calc 1. Not more difficult in terms of concepts [ it’s just an extension of integration techniques plus series ], but more tedious algebra.

Is calculus really that hard?

Calculus is a very difficult subject and one that a lot of students have trouble with. Calculus is a very difficult subject and one that a lot of students have trouble with. Indeed, it is the toughest course at YSU. If it is any consolation, you should remember that, generally, only strong math students take Calculus.

Can calculus be self taught?

You can teach yourself calculus. It won’t be easy and requires self-discipline and knowledge in algebra, geometry, and trig. However, the resources are out there, but the motivation must come from within.

Is Trig harder than calculus?

The rigorous study of calculus can get pretty tough. If you are talking about the “computational” calculus then that is a lot easier though. On the other hand, computational trig as it’s generally taught in high school is a lot easier than calculus.

Is statistics better than calculus?

Calculus is more useful for students pursuing majors in science or engineering. Statistics, on the other hand, is not only necessary for being an informed citizen, but is useful for almost every major and career. Calculus simply lacks this universal applicability.

Is Statistics harder than algebra 2?

a fundamental course in statistics, then, generally, statistics is more difficult. Algebra concepts are much easier to grasp, Stats concepts are harder to grasp but the work itself at an INTRO level stat class will be easier as most of it is just memorizing a bunch of formulas and plugging them in.

Is there a lot of math in statistics?

Originally Answered: Is statistics a field of math? No. Statistics is its own field separate from mathematics similar to physics. Although the two are closely related because the concept of probability is indeed studied in mathematics, and statistics makes use of many tools of analysis/calculus.

Why is Navier Stokes unsolvable?

In particular, solutions of the Navier–Stokes equations often include turbulence, which remains one of the greatest unsolved problems in physics, despite its immense importance in science and engineering. Even more basic properties of the solutions to Navier–Stokes have never been proven.

What are the 7 Millennium Problems?

Clay “to increase and disseminate mathematical knowledge.” The seven problems, which were announced in 2000, are the Riemann hypothesis, P versus NP problem, Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier-Stokes equation, Yang-Mills theory, and Poincaré conjecture.

What happens if P vs NP is solved?

If P=NP, then all of the NP problems can be solved deterministically in Polynomial time. If you could solve clique with a polynomial time algorithm, this would prove that P=NP, and then you could also use your method for solving clique to solve all of the other problems on that wiki-list, as an implication.

Is P equal to NP?

The statement P=NP means that if a problem takes polynomial time on a non-deterministic TM, then one can build a deterministic TM which would solve the same problem also in polynomial time.

What does P vs NP stand for?

nondeterministic polynomial time

What is the hardest math problem in the world?

Riemann Hypothesis

What is NP short for?

NP means “No Problem.” The abbreviation NP is widely used in text-based messaging with the meaning “No Problem.” NP is typically used as a positive response to a request (i.e., to say “Yes”) and as a response to someone saying thank you (i.e., to say “You’re welcome”).

How do you prove a problem is NP-hard?

To prove that problem A is NP-hard, reduce a known NP-hard problem to A. In other words, to prove that your problem is hard, you need to describe an ecient algorithm to solve a dierent problem, which you already know is hard, using an hypothetical ecient algorithm for your problem as a black-box subroutine.

What is NP-hard problem with example?

Examples. An example of an NP-hard problem is the decision subset sum problem: given a set of integers, does any non-empty subset of them add up to zero? That is a decision problem and happens to be NP-complete.

How do you prove P NP?

One way to prove that P = NP is to show that the complexity measure TM (n) for some NP problem, like the 3-CNF-SAT problem, cannot be reduced to a polynomial time. We will show that the 3-CNF-SAT problem behaves as a common safe problem and that its complexity is time dependent.

Is P NP solvable?

P problems are easily solved by computers, and NP problems are not easily solvable, but if you present a potential solution it’s easy to verify whether it’s correct or not.

What is the difference between P and NP problems?

P = the set of problems that are solvable in polynomial time by a Deterministic Turing Machine. NP = the set of decision problems (answer is either yes or no) that are solvable in nondeterministic polynomial time i.e can be solved in polynomial time by a Nondeterministic Turing Machine[4].

Can NP complete problems be solved?

If any NP-complete problem has a polynomial time algorithm, all problems in NP do. The set of NP-complete problems is often denoted by NP-C or NPC. Although a solution to an NP-complete problem can be verified “quickly”, there is no known way to find a solution quickly.

Are NP-hard problems solvable?

A problem is NP-hard if all problems in NP are polynomial time reducible to it, even though it may not be in NP itself. If a polynomial time algorithm exists for any of these problems, all problems in NP would be polynomial time solvable. These problems are called NP-complete.

What is the difference between NP-hard and NP-complete problems?

A problem X is NP-Complete if there is an NP problem Y, such that Y is reducible to X in polynomial time….Difference between NP-Hard and NP-Complete:

NP-hard	NP-Complete
To solve this problem, do not have to be in NP .	To solve this problem, it must be both NP and NP-hard problems.
Do not have to be a Decision problem.	It is exclusively a Decision problem.

Is traveling salesman NP-complete?

Traveling Salesman Optimization(TSP-OPT) is a NP-hard problem and Traveling Salesman Search(TSP) is NP-complete. However, TSP-OPT can be reduced to TSP since if TSP can be solved in polynomial time, then so can TSP-OPT(1).

Is traveling salesman NP-hard?

The travelling salesman problem (also called the traveling salesperson problem or TSP) asks the following question: “Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the origin city?” It is an NP-hard problem in …

Why is TSP NP-hard?

Thus we can say that the graph G’ contains a TSP if graph G contains Hamiltonian Cycle. Therefore, any instance of the Travelling salesman problem can be reduced to an instance of the hamiltonian cycle problem. Thus, the TSP is NP-Hard.

Is vertex cover NP-complete?

Its decision version, the vertex cover problem, was one of Karp’s 21 NP-complete problems and is therefore a classical NP-complete problem in computational complexity theory.

Are NP-complete problems Decidable?

There are certain NP-Hard problems that also exist in NP. They are decidable, verifiable in polynomial time and are a polynomial reduction of an NP problem. These are said to be NP-Complete. Any NP-complete problem, using a polynomial-time function, can be reduced to SAT.

Is clique problem NP-complete?

In computer science, the clique problem is the computational problem of finding cliques (subsets of vertices, all adjacent to each other, also called complete subgraphs) in a graph. Most versions of the clique problem are hard. The clique decision problem is NP-complete (one of Karp’s 21 NP-complete problems).

Is Sudoku an NP-complete problem?

Mathematical context The general problem of solving Sudoku puzzles on n2×n2 grids of n×n blocks is known to be NP-complete. The Sudoku graph has 81 vertices, one vertex for each cell. The vertices are labeled with ordered pairs (x, y), where x and y are integers between 1 and 9.

Is there an algorithm for Sudoku?

The Algorithm One algorithm to solve Sudoku puzzles is the backtracking algorithm. Essentially, you keep trying numbers in empty spots until there aren’t any that are possible, then you backtrack and try different numbers in the previous slots.

Is chess a NP?

For this reason games like chess cannot themselves be NP-complete, as they only have a finite (albeit unthinkably large) number of possible positions.

What is NP completeness problem?

NP-complete problem, any of a class of computational problems for which no efficient solution algorithm has been found. Many significant computer-science problems belong to this class—e.g., the traveling salesman problem, satisfiability problems, and graph-covering problems.

What is N and P NP-complete problems?

What are NP, P, NP-complete and NP-Hard problems? P is set of problems that can be solved by a deterministic Turing machine in Polynomial time. NP is set of decision problems that can be solved by a Non-deterministic Turing Machine in Polynomial time. NP-completeness applies to the realm of decision problems.

Is N Queens NP-complete?

Ian Gent, Christopher Jefferson and Peter Nightingale have shown that a classic chess puzzle is NP-Complete. Their paper “Complexity of n-Queens Completion” was published in the Journal of Artificial Intelligence Research on August 30.

What is 8 queen problem in DAA?

The eight queens puzzle is the problem of placing eight chess queens on an 8×8 chessboard so that no two queens threaten each other; thus, a solution requires that no two queens share the same row, column, or diagonal.
