Traveling salesman problem: herustics and empirical evaluation
(2015) Kaya, Ahmet Sedat
In this thesis, three different algorithms with different perspectives (Close Couple, Worm, and Spider Web) has been developed to solve the Symmetric Traveling Salesman (TSP) heuristically. Improved algorithms with different data sets Distance Rate, Target have been tested. The running time and value of the solution have been compared. In this context, several steps of evaluation were used for the comparison and improvement of algorithms. After each evaluation step, one candidate algorithm is eliminated. Eventually, an improved version of the Spider Web algorithm is the winner of this contest.
Combined jpeg with dwt for image compression
(2012) Nabeel Dara, Omar
The main idea for this research is apply JPEG technique with enhanced quantization, on Discrete Wavelet Transformation (DWT). The DWT minimize the size of the image into convert the image into LL, HL, LH and HH sub-bands. The LL sub-band represents approximately original image, and then applied JPEG technique on the LL sub-band, then applied quantization to increase number of zeros. Finally apply Sequential Search Coding on the JPEG matrix for coding. The Sequential Search Coding work to convert group of data into single floating point value by using Key.
