3 One implementation for the sparse matrix is described in Section 12.3 Another im- plementation is a hash table whose search key is a concatenation of the matrix coor- dinates. 1.7 Every problem certainly does not have an algorithm. As discussed in Chapter 15, there are a number of reasons why this might be the case. Some problems don’t have a suf fi ciently clear de fi nition. Some problems, such as the halting problem, are non-computable. For some problems, such as one typically studied by arti fi cial intelligence researchers, we simply don’t know a solution. 1.8 We must assume that by “algorithm” we mean something composed of steps are of a nature that they can be performed by a computer. If so, than any algorithm can be expressed in C ++ . In particular, if an algorithm can be expressed in any other computer programming language, then it can be expressed in C ++ , since all (suf fi ciently general) computer programming languages compute the same set of functions.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
