For this workshop, you should choose a research topic, then search for it and check if it has been studied before evaluating its relevance and feasibility, and finally refine the idea, to get the new idea. Repeat this process five times, where each time, the idea is the refined idea from the last step. Submit your workshops as a PDF as follows: Lastname_firstname_studentID.PDF NOTE: Please make sure to write down the idea at each step. Explain the process and result of the search and your refinement process at each step.
