nonrealisable

Nonrealisable refers to a concept or idea that cannot be implemented or achieved in practice, despite being theoretically possible. This term is often used in fields such as engineering, economics, and computer science to describe situations where a proposed solution or strategy is not feasible due to various constraints, such as technological limitations, resource availability, or regulatory requirements.

In engineering, for example, a nonrealisable design might be one that requires materials or technologies that are not currently available or too expensive to produce. In economics, a nonrealisable policy could be one that is theoretically sound but impractical to implement due to political, social, or economic factors. In computer science, a nonrealisable algorithm might be one that requires an impractical amount of computational resources or time to execute.

The concept of nonrealisability is closely related to that of feasibility, which refers to the practicality of a plan or course of action. While feasibility analysis considers various factors to determine whether a project can be successfully completed, nonrealisability specifically addresses the question of whether a project can be implemented at all, given the existing constraints and limitations.
