ADS, Sanjay Goel, JIITU, Even sem 2006-07 Advanced Data StructuresLect #1Course description and brief review of DS.Programming Assignment (5 Marks): Work on pending DS assignment as announcedby Lab instructorsLect #2Hardware efficiency Vs Data size wrt to time complexity of processing algorithm..Lect #3Algorthmic Visualisation with the help of animated graphics. Cases of Bubblesort,Insertion sort, and selection sort. Ref: SedgewickProgramming Assignment (5 marks): WAP to embed animated visualization intoyour programs of Bubble/insertion/ and Selection sort. Work in the group of twomembers for two of these sorters and do one independently. Use creative forms forvisualizing and do not use the technique discussed in the class.Lect #4Project possibilities.Overarching projects 1. Computing for empowerment especially ignored sections of society (visually challenged/hearing challenged/elders/homemaker women/…) and application domain. 2. Computing for creating opportunities enhanced self expression and pleasure for different categories of people with different kinds of tastes and talents. e.g musicians/painters/story tellers/designers (any kind)/DJ/Cartoonist/Elderly/ mothers/ homemaker women/….. 3. Information indexing, retrieval, classification, mixing, visualization, and transformation with reference to large text, image, video, graphics, audio, mix- media. 4. Computer Games (preferably based on sensitive, sensible and culturally grounded plots). You can even write a game simulator (without sophisticated graphics) that can be developed into a full Game with sophisticated graphics later. 5. Cultural Exploratorium 6. Digital or analog circuit simulators. 7. and so on….
ADS, Sanjay Goel, JIITU, Even sem 2006-07 1. Ms. Anjali Sehgal is the Chief project faculty coordinator. All lab instructors in ADS and OOPS will coordinate their respective students. Selected 4th year and 3rd students will mentor the projects. 2. Formulate intra-batch groups. Inter-batch project groups will be permitted only if there is at least 1hr common lab timing of ADS/OOPS. It is also possible to form groups if one member is free at the time other’s lab. It is essential that all group members show their progress to assigned lab instructor on weekly basis during lab hours. One project group should ideally have 2/3 students. If you have idea for a larger project, divide it into smaller sub-project for sub teams that will work nearly independently.Look at the final year projects of senior batches. 1.
