Examples of "Undecidable"

In computability theory, the halting problem is an example of an undecidable problem: it is impossible to write an algorithm that can determine, given an arbitrary program and input, whether the program will run forever or eventually halt.
The problem of determining whether a given logical statement is true or false is undecidable in general, as it may depend on a contradictory set of axioms or the statement may be undecidable in a particular model of mathematics.
In cryptography, the safety of certain encryption algorithms like RSA and elliptic curve cryptography rely on problems being undecidable, making it infeasible to easily factor the large numbers used in encryption.
The question of whether a given high-level programming language algorithm is valid or not is formally undecidable because there exist algorithms that the language is able to confirm valid, but fails to recognize certain well-known invalid algorithms.
The trademark registry of the World Intellectual Property Organization (WIPO) considers the question of what is generic vs. what is a trade mark to be undecidable, as a generic term can become proprietary if heavily commercialized.
