Level of complexity is a measure, which describes characteristics of organizational or social system. In management we can distinguish following levels of system complexity:
- complicated system (e.g. machine, computer)
- random system (market, customer behaviour, chaotic changes in financial markets)
- organized complexity (organizational structure, processes, principles, algorithms)
- self-organized complexity (adaptive systems, organizational flexibility, innovation)
Level of complexity is a measure of how difficult a problem or task is to complete. It is often used to assess the difficulty of computer algorithms, but can also be applied to other areas such as problem solving and decision making. The most common way of measuring complexity is to count the number of steps or operations that must be completed in order to solve the problem. This can be done by counting the number of instructions required to complete the task or by evaluating the amount of time and resources necessary to solve the problem.
The level of complexity is an important concept in computer science and can be used to compare the difficulty of different algorithms. It is also useful for determining the amount of resources and time needed to complete a task. Knowing the level of complexity of a problem can help to make the decision on which algorithm is best for a particular task.
Example of Level of complexity
The following are examples of how the level of complexity can be applied:
- Low complexity algorithms require fewer steps and resources, and can be solved quickly. A sorting algorithm, for example, may require only a few lines of code and take only a few seconds to complete.
- Medium complexity algorithms require more steps and resources, and may take longer to complete. A graph traversal algorithm, for example, may require more lines of code and take a few minutes or more to complete.
- High complexity algorithms require the most steps and resources, and can be quite difficult and time consuming to solve. A travelling salesman problem, for example, may require a large number of lines of code and take hours or even days to complete.
Formula of Level of complexity
The formula for calculating the level of complexity of an algorithm is the following:
- Complexity = Time taken + Resources used
This formula takes into account both the amount of time it takes to complete a task and the amount of resources used. By taking both of these factors into account, it is possible to determine the level of complexity of an algorithm.
For example, if an algorithm takes 10 seconds to complete and uses 10 megabytes of memory, its complexity would be equal to 10 + 10 = 20. This would be considered a medium complexity algorithm.
When to use Level of complexity
Level of complexity is most often used in the field of computer science when evaluating the difficulty of algorithms. It is also used in problem solving and decision making, as it can help to determine the amount of resources and time needed to complete a task. Knowing the complexity of a problem can help to make the decision on which algorithm is best for a particular task.
Categorization
There is no such control system that would be universal for use in all circumstances. From what circumstances the organization faces, it is possible to apply a given control system. An accidental project that is likely to be important for control is related to conventional control documentation. For the research on the design of management control one of the dominant paradigms has become the contingency theory. A method for categorizing research has been introduced, which offers great opportunities for future research.
The level of complexity of the analysis classifies scientific articles on control. Research on internal control is carried out in a fragmented way. This is one of the main weaknesses of this study. At the same time, one conditional factor and one control attribute examine a lot of research. In order to determine the effectiveness of the control system design, it may be crucial to understand the interaction between multiple condition and control.
The simplest emergency analysis attempts to correlate the factor with the control system attribute. However, a more complex analysis can analyze many conditional and coercive factors simultaneously. The development and testing of a comprehensive model that includes multiple control systems, many conditional and resultant variables should be the ultimate goal of conditional testing.
The appropriate controls, cases and tests are described in the first place according to the level of their complexity. Next, the definition of the formal control system is discussed. The third step is to analyze the characteristics of the conditional model and list the conditional variables that were included in the control studies. Discussing previous works on conditional control and introducing the classification framework for these studies is a fourth step.The final stage is to assess some of the weaknesses of current conditional control studies and discuss the possibilities for future research[1].
Steps to assess Level of complexity
- Count the number of instructions required to complete the task: The first step in measuring the complexity of a task is to count the number of instructions required to complete it. This is typically done by counting the number of steps in the algorithm or the amount of lines of code necessary to complete the task.
- Evaluate the amount of time and resources needed: The second step is to evaluate the amount of time and resources needed to complete the task. This is usually done by comparing the amount of time and resources required for the task to those of a similar task.
- Compare the difficulty of different algorithms: The third step is to compare the difficulty of different algorithms. This is typically done by looking at the number of instructions required to complete the task, the amount of time and resources necessary, and the ease of understanding of the algorithm.
Advantages of Level of complexity
- It provides an objective measure of the difficulty of a problem.
- It can be used to compare the difficulty of different algorithms.
- It helps to determine the amount of resources and time needed to complete a task.
- It can help to make the decision on which algorithm is best for a particular task.

It is one of the most common ways of assessing complexity, but there are also other approaches such as computational complexity and algorithmic complexity. Understanding the level of complexity is important for making the decision on which algorithm to use for a particular task.
