 Non-constructive algorithm existence proofs

Non-constructive algorithm existence proofs refer to a type of proof that establishes the existence of a mathematical object or solution without providing a method for explicitly constructing it. In other words, these proofs show that at least one object with certain properties exists, but they do not give an algorithm or step-by-step procedure to find or build that object. ### Characteristics of Non-constructive Existence Proofs: 1. **Existential Quantification**: Non-constructive proofs often use existential quantifiers.
