What is decision problem?

A decision problem is a specific type of problem in computational theory and mathematics that asks whether a given statement or proposition is true or false based on certain parameters. It typically involves yes-or-no questions that can be posed in the context of algorithms, logic, or formal systems. Decision problems are important in areas such as complexity theory and algorithm design, as they help classify problems based on their computational difficulty. Examples include determining whether a number is prime or whether a given graph is connected.
