    nstructions For this assignment, you will be building a Ray Tracer using Python. The choice of which of these languages is up to you, but keep in mind that language-specific support is not provided (you should use the language you can locally support and are comfortable coding in). The system only needs to handle the rendering of ellipsoids, with a fixed camera situated at the origin in a right-handed coordinate system, looking down the negative z-axis. Local illumination, reflections, and shadows will also need to be implemented. The program should take a single argument, which is the name of the file to be parsed. Make sure your executable has the name “” (or equivalent for the language you choose) and that we can run it as in the following examples: > or > java ...

    1. Project Description You are a member of the coast guard force in charge of a rescue boat that goes into the sea to rescue other sinking ships. When rescuing a ship, you need to rescue any living people on it and to retrieve its black box after there are no more passengers thereon to rescue. If a ship sinks completely, it becomes a wreck and you still have to retrieve the black box before it is damaged. Each ship loses one passenger every time step. Additionally, each black box incurs an additional damage point every time step once the ship becomes a wreck. One time step is counted every time an action is performed. You reach your goal when there are no living passengers who are not rescued, there are no undamaged boxes which have not been retrieved, and the rescue boat is not carrying a...

    Structural Test Data Generation Exercise This piece of coursework is based around the problem of using search-based strategies to automatically generate test data to achieve a level of coverage (in this exercise we will focus on statement coverage). The exercise is based around two methods included at the end of this page: one which takes integer inputs and the other yet to be defined (but you need to tackle the first problem before moving onto the second). The main challenge with this problem is that unlike the other situations we have explored where all the necessary data was available in a file, here the GA needs to interact with the program under test and execute it to establish the fitness values of the population. So the program under test needs to be instrumented (have code inserted...
