Sunday 13th April 2014: 9.55pm. Well "Networks 4" which is the second last topic of my OU graph algorithms course is the first of this course to defeat me! They have you optimising an electrical system graph with partial differential equations in it using matrices, and that part I can do. The problem is what is the answer they want, and that final part of doing Gaussian elimination on the matrices is fine but I am defeated when reducing the differential equations (which are time and starting state dependant) into a final state equation. I'm not an electrical engineer and in this two week long section they basically dumped two undergraduate years of electrical theory on you and it's too much for me to grok in the very few hours I have for this. So I'm accepting the likely bare pass grade and moving on. Which sucks. But, pardoning the pun, moving on is a good example of me optimising my study 'graph' har har.
