Addition and scalar multiplication shall be supported as well. No linear algebra functions are sought for (e.g. inverse, linear solving, svd etc.). The focus is on correctness, efficiency, and a clean and convincing software design - show us your C++ skills ;-) No 2: You are given a gray scale image which represent the oil distribution in a certain area (pixel value 0: 0 liters of oil, pixel value 255: 255 liters of oil). You can place 64 "drills" in this area. Each drill will extract the oil in a circular area of radius 25 pixels. Please try to find the optimal distribution for the drills, for each of the three images in this archive. Provide your solution as three text files with drill center coordinates, like the example file "drilling_plan_example.txt". You can check out the program "evaluate_plan.py" in this archive.
