    The main purpose of a problem statement is to identify and explain the problem. [3] [4] Another function of the problem statement is as a communication device. [3] Before the project begins, stakeholders verify the problem and goals are accurately described in the problem statement. Once approved, the project reviews it.

    en.wikipedia.org/wiki/Problem_solving

    Problem-solving processes differ across knowledge domains and across levels of expertise. [60] For this reason, cognitive sciences findings obtained in the laboratory cannot necessarily generalize to problem-solving situations outside the laboratory. This has led to a research emphasis on real-world problem solving, since the 1990s.

    The modern statement of the Hodge conjecture is: Let X be a non-singular complex projective variety. Then every Hodge class on X is a linear combination with rational coefficients of the cohomology classes of complex subvarieties of X. The official statement of the problem was given by Pierre Deligne. [12]
