4. Give precise formulations for each of the following as constraint satisfaction problems: A. Rectilinear floor-planning: find non-overlapping places in a large rectangle for a number of smaller rectangles. Ans: B. Class scheduling: There is a fixed number of professors and classrooms, a list of classes to be offered, and a list of possible time slots for classes. Each professor has a set of classes that he or she can teach. C. Hamiltonian tour: given a network of cities connected by roads, choose an order to visit all cities in a country without repeating any.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
