# Task Complexity

Each task in the system is associated with a **complexity metric**, which quantifies the computational effort required for its execution. The task's complexity is calculated as the sum of the complexities of all its instructions:

* The complexity of a task is determined by adding up the complexity values of its individual instructions.
* This metric helps evaluate and allocate tasks to actors with appropriate resources.
