SUMMARY:7 PM – USACO Bronze – Darin
DESCRIPTION:What We Did Today:\n\nWent over the Balancing Bacteria optimal solution over greedy search\n\nHomework:\n\nCode up the optimal solution(s) for Balancing Bacteria\, and submit your answer to the webpage and google drive when you are finished\nproblem: https://usaco.org/index.php?page=viewproblem2&cpid=1372 \nNote on the optimal solution:\nIn class we talked about how to derive the accumulation by analyzing the solution\, and estimating the remainder needed. \nNote that I did not account for the remainder properly because the remainder is computed one step ahead in time (meaning after the first update we assume no remainder)\, but this makes it hard to compute the remainder as we need more variables to keep track for proper remainder counting \nInstead\, on every update\, it suffices for us to increment the accumulation by the netSprayValue (everytime we do a target spray\, what is the net target spray value) + currentSprayValue \nHowever I recommend practicing with deriving the update rule for the accumulation\, analyzing the numbers shown by hand accounting the needed accumulation then seeing if you can come up with a pattern for the accumulation shown. This is important especially during competitions where you will be asked to come up with a formula you may have not seen before but is in similar spirit.\n\nNotes:\nYou can reach out to me at ddjapri@ayclogic.com if you have any questions! \nYou can find class notes here (Tues7PM_IntroToCompProgramming is our excel sheet for visuals).
