An intractable problem, also known as an unsolvable problem or an intractable issue, refers to a problem or situation that is exceptionally difficult or impossible to solve, manage, or resolve using existing knowledge, resources, or methods
All intractable problems can be considered wicked problems
However, not all wicked problems are necessarily intractable
Some wicked problems may have more feasible solutions, while others may be exceptionally challenging to address but not entirely intractable
