{{Otheruses}}{{Wiktionary}}A
problem is an "
issue" or obstacle which makes it difficult to achieve a desired goal, objective or purpose. It refers to a situation, condition, or issue that is yet unresolved. In a broad sense, a problem exists when an individual becomes aware of a significant difference between what actually is and what is desired.
Problem solving
Every theoretical problem asks for an
answer or solution. Trying to find a solution to a problem is known as
problem solving. That is, a problem is a gap between an actual and desired situation. The time it takes to solve a problem is a way of measuring
complexity.
(1) Many problems have no discovered solution and are therefore classified as an
open problem.{{See also|List of unsolved problems}}From the mid 20th century, the field of
theoretical computer science has explored the use of computers to solve problems.
Examples
- Mathematical problem is a question about mathematical objects and structures that may require a distinct answer or explanation or proof. Examples include word problems at school level or deeper problems such as shading a map with only four colours.
- In society, a problem can refer to particular social issues, which if solved would yield social benefits, such as increased harmony or productivity, and conversely diminished hostility and disruption. {{See also|Wicked problem}}
- In business and engineering, a problem is a difference between actual conditions and those that are required or desired. Often, the causes of a problem are not known, in which case root cause analysis is employed to find the causes and identify corrective actions.
- In chess, a problem is a puzzle set by somebody using chess pieces on a chess board, for others to get instruction or intellectual satisfaction from determining the solution.
- In theology, there is what is referred to as the Synoptic Problem, which includes in its discourse a concern for assumptions of historical accuracy that are challenged by apparent contradictions in the Gospels' accounts of allegedly historical events.
- In academic discourse a problem is a challenge to an assumption, an apparent conflict that requires synthesis and reconciliation. It is a normal part of systematic thinking, the address of which adds to or detracts from the veracity of a conclusion or idea.
- An optimization problem is finding the best solution from all feasible solutions. A good example of this type of problem is the travelling salesperson problem which is based on calculating the most efficient route between many places
- In computability theory a decision problem requires a simple yes-or-no answer.
- In rock climbing a problem is a series of rocks that forces the climber to climb.
- In reading, a problem is a combination of a series of words with the overall plotline, which the reader must attempt to decipher.
- In walking, a mobility problem is presented. Motion is achieved via mechanical interaction of the legs and a surface.
