This contribution shows the experimental results of the EE2-4.6, which tests the performance of the Huffman coding and the simulated annealing for CCALF as proposed in JVET-AJ0349. This also includes (in test 4.6b) the results of the combination with the EE2-4.1, which includes restrictions on ALF coefficient values and additional scaling factor for ALF, the coefficient derivation using simulated annealing and the coefficient signaling using Huffman coding. The above tests are implemented on the top of ECM-15.0 and tested under common test conditions (CTC). The overall results of EE2-4.6b are as follows:
