A problem can be demonstrated to be NP-hard by showing that it is at least as difficult as any other problem in the NP complexity class. This is typically done by reducing a known NP-hard problem to the problem in question, showing that a solution to the problem in question would also solve the known NP-hard problem.

How can one demonstrate that a problem is NP-complete?
One can demonstrate that a problem is NP-complete by showing that it belongs to the NP complexity class and that it is at least as hard as any other problem in NP. This can be done by reducing a known NP-complete problem to the problem in question through a polynomial-time reduction.
How can one demonstrate that a problem is in the complexity class P?
One can demonstrate that a problem is in the complexity class P by showing that it can be solved in polynomial time by a deterministic Turing machine. This means that the problem's solution can be found in a reasonable amount of time that grows at most polynomially with the size of the input.
How can one demonstrate the effectiveness of an algorithm?
One can demonstrate the effectiveness of an algorithm by analyzing its performance in terms of speed, accuracy, and efficiency compared to other algorithms or benchmarks. This can be done through testing the algorithm on various datasets and measuring its outcomes to determine its effectiveness in solving a specific problem.
How can one demonstrate the correctness of an algorithm?
One can demonstrate the correctness of an algorithm by using mathematical proofs and testing it with various inputs to ensure it produces the expected output consistently.
How can one demonstrate that a grammar is unambiguous?
One can demonstrate that a grammar is unambiguous by showing that each sentence in the language has only one possible parse tree, meaning there is only one way to interpret the sentence's structure.
