  2. Problem finding - Wikipedia

    en.wikipedia.org/wiki/Problem_finding

    Scholars distinguish between well-defined and ill-defined problems. Briggs and Reinig defined a well-defined solution in terms of space solution space. Pretz, Naples, and Sternberg defined a well-defined problem as one for which the parts of the solution are closely related or clearly based on the information given. Problem finding applies to ...

  3. Well-defined expression - Wikipedia

    en.wikipedia.org/wiki/Well-defined_expression

    In particular, the term well-defined is used with respect to (binary) operations on cosets. In this case, one can view the operation as a function of two variables, and the property of being well-defined is the same as that for a function. For example, addition on the integers modulo some n can be defined naturally in terms of integer addition.

  4. Problem solving - Wikipedia

    en.wikipedia.org/wiki/Problem_solving

    The term problem solving has a slightly different meaning depending on the discipline. For instance, it is a mental process in psychology and a computerized process in computer science. There are two different types of problems: ill-defined and well-defined; different approaches are used for each.

  5. Well-posed problem - Wikipedia

    en.wikipedia.org/wiki/Well-posed_problem

    Problems in nonlinear complex systems (so-called chaotic systems) provide well-known examples of instability. An ill-conditioned problem is indicated by a large condition number. If the problem is well-posed, then it stands a good chance of solution on a computer using a stable algorithm. If it is not well-posed, it needs to be re-formulated ...

  6. Condition number - Wikipedia

    en.wikipedia.org/wiki/Condition_number

    A problem with a low condition number is said to be well-conditioned, while a problem with a high condition number is said to be ill-conditioned. In non-mathematical terms, an ill-conditioned problem is one where, for a small change in the inputs (the independent variables) there is a large change in the answer or dependent variable. This means ...

  7. Design thinking - Wikipedia

    en.wikipedia.org/wiki/Design_thinking

    Designing deals with design problems that can be categorized on a spectrum of types of problems from well-defined problems to ill-defined ones to problems that are wickedly difficult. [14]: 39 In the 2010s, the category of super wicked global problems emerged as well. [15]

  8. Lists of problems - Wikipedia

    en.wikipedia.org/wiki/Lists_of_problems

    The following articles contain lists of problems: List of philosophical problems; List of undecidable problems; Lists of unsolved problems; List of NP-complete problems;

  9. Problem structuring methods - Wikipedia

    en.wikipedia.org/wiki/Problem_structuring_methods

    In discussions of problem structuring methods, it is common to distinguish between two different types of situations that could be considered to be problems. [17] Rittel and Webber's distinction between tame problems and wicked problems (Rittel & Webber 1973) is a well known example of such types. [17]
