With a lens of systems thinking, project complexity can be defined as an intricate arrangement of the varied interrelated parts in which the elements can change and evolve constantly with an effect on the project objectives. [2] The identification of complex projects is specifically important to multi-project engineering environments. [3]
A logical postulation that evades resolution, an intricate and difficult problem. Literature. Conundrum (Lyons novel), a 1994 Doctor Who novel by Steve Lyons;
For example, some difficult problems need algorithms that take an exponential amount of time in terms of the size of the problem to solve. Take the travelling salesman problem , for example. It can be solved, as denoted in Big O notation , in time O ( n 2 2 n ) {\displaystyle O(n^{2}2^{n})} (where n is the size of the network to visit – the ...
A complex system is a system composed of many components which may interact with each other. [1] Examples of complex systems are Earth's global climate, organisms, the human brain, infrastructure such as power grid, transportation or communication systems, complex software and electronic systems, social and economic organizations (like cities), an ecosystem, a living cell, and, ultimately, for ...
Tacit knowledge can be defined as skills, ideas and experiences that are possessed by people but are not codified and may not necessarily be easily expressed. [5] With tacit knowledge, people are not often aware of the knowledge they possess or how it can be valuable to others.
Another definition is "a problem whose social complexity means that it has no determinable stopping point". [2] Moreover, because of complex interdependencies, the effort to solve one aspect of a wicked problem may reveal or create other problems. Due to their complexity, wicked problems are often characterized by organized irresponsibility.
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
A decision problem H is NP-hard when for every problem L in NP, there is a polynomial-time many-one reduction from L to H. [1]: 80 Another definition is to require that there be a polynomial-time reduction from an NP-complete problem G to H.
