Overview

Mathematical models in the natural sciences take many shapes and forms. The moment they become more complicated than tracking a few variables over time, we have to put away our Excel spreadsheets and make use of a solid foundation in computational science. The course establishes this foundation by introducing data structures and algorithms used in everyday scientific computing using examples in the python scripting language. By the end of the Semester, students will be able to navigate the Linux command-line to go from a mathematical model to a numerical solution. Best practices for working with computer code and visualizing data will also be covered.

Topics

1. Languages
   • bash (shell)
   • python (scripting)
   • stack & register-based machine languages: overview of C and Fortran syntax & compiling with gcc, ‘thread safety’
   • Shared libraries & language inter-operability (FFI)
2. Algorithms
   • Horner’s algorithm for polynomials
   • Newton’s root finding algo.
   • Overview of general optimization algo-s (example: linear & nonlin. least-squares)
   • Numerical integration (scripted, plus gnu ODE)
   • Communication (how HTTP get/put works)
3. Data Structures
   • Linked Lists
   • Trees (file system hierarchies)
   • Graphs
   • Arrays (dense & sparse) example: vectors & rotations / transpositions, densities and difference operators
4. Presentation & visualization
   • Flat CSV files (and excel)
   • Working with binary data
   • Python matplotlib (2D images)
   • Binning histograms & weighted averages
5. Best Practices
   • High-level code design (modularity, interface specifications, unit testing, etc.)
   • Code audit: open-source libraries, ex. Gnu Scientific Library, qsort in libc, Boost
   • Source code versioning (example: git or mercurial)
   • gdb & execution profiling
   • documentation
   • Makefiles

Grading

Grading Scale (out of 400 points possible)

• (280 U / 330 G) Points Possible:
  • 9 homework assignments (10 points per homework)
  • 14 in-class assignments / quizzes (10 points per week)
  • 2 projects / competitions (50 points per project)
  • Undergraduates must complete 1 project, graduates must complete 2

• Important Rules
  • For maximum benefit, homework should be done on-time. However, homework will be allowed to be re-submitted at any time for full credit, but must present a unique solution to previous work from yourself or others.
  • All work must cite co-group members (if any) and the source of any code snippets used online.

Grading Rationale

Homework points will only be awarded for correct, working code and correct algorithmic analysis, while the homework problems will become progressively tougher. Undergraduates should be able to pass the course with an A if they have correctly answered most of the homework, appear at class prepared and on-time, and made a strong attempt at one of the projects. Graduate students should both perform well on the homework and successfully complete one or two projects. The re-grading for homework allows making up for missed assignments, and encourages returning to core concepts at a later point in the class. Students who have put in the studying effort, completed significant portions of the homework and projects both in- and out of class have thus demonstrated introductory programming proficiency.
