Hobart and William Smith Colleges

In the Department of Mathematics and Computer Science

Computers are an integral part of today's society, and understanding how to effectively use the power of computing is increasingly important. The study of computer science also promotes rigorous thinking and problem-solving ability - beneath the technical knowledge necessary for working with computers, computer science is, at its core, very much the study of how to solve problems. Many students who major in computer science go on to graduate school or to work in related professions. For other students, computer science is a good choice for a second major or minor, in combination with another major from any of the Colleges' academic divisions. Regardless of field, students often find that the skills they have gained studying computer science are highly sought-after by employers. To meet the challenges, opportunities, and responsibilities encountered after graduation, computer science majors are encouraged to obtain a broad but firm foundation in the discipline. In a rapidly growing and changing field, the department offers a range of courses that enable majors to use modern technology, to understand its applications across a broad range of disciplines, and to understand the fundamental and enduring principles underlying those applications.

The Department of Mathematics and Computer Science offers two majors in computer science (B.A. and B.S.) and a minor in computer science. In addition to the specific courses listed below, other courses may be approved by the department for credit toward the major. To be counted toward the major or minor, all courses must be passed with a grade of C- or better; credit/no credit courses cannot be taken toward the major or minor.

Prerequisite: CPSC 327 or 329. (Offered occasionally)

CPSC 450 Independent Study

CPSC 451 Capstone Independent Study
Capstone Independent Study can be taken in the senior year as the capstone experience in the computer science major. A student who would like to pursue this option must find a faculty sponsor, as for any independent study, and must submit a written proposal for the independent study. The proposal must be approved by the department chair. A Capstone Independent Study must satisfy the general criteria for a computer science capstone course: a significant project integrating theory and practice, and utilizing software development principles, practices, and tools; a significant design / planning experience where students must weigh alternatives and choose an appropriate approach; a significant written, oral, and/or visual presentation of work beyond the program code itself. Note that in some cases an Honors course, CPSC 495 that does not lead to a completed Honors project might be converted into a CPSC 451 course instead of CPSC 450; this will require approval by the department chair.

CPSC 456 1/2 Credit Independent Study

CPSC 489 Capstone Experience To fulfill the capstone experience in computer science, students must take one course designated as a 'capstone course' during their senior year or successfully complete honors (CPSC 495). Courses numbered 400 and above (except CPSC 450 and CPSC 499) are capstone courses. To register for CPSC 451 (Capstone Independent Study), students must submit a written proposal to the instructor and to the department chair explaining how the capstone criteria will be met.
