The reasons are many e.g., visualize mathematical problems, correlate real-world problems on a conceptual level, are flexible, simple to use, accessible from anywhere, etc. However, there is still room for improvement. Computer algebra system (CAS) optimization is the set of best practices and techniques to keep the CAS running optimally. Best practices are related to how to carry out a mathematical task or configure your system. In this paper, we are going to examine these techniques. The documentation sheets of CASs are the source of data that we used to compare them and examine their characteristics. The research results reveal that there are many tips that we can follow to accelerate performance.展开更多

According to UNAIDS report on the global AIDS epidemic in 2016, the estimated number of people living with HIV rose from 7.5 million in 2010 to 36.7 million in 2015. Furthermore, drug-resistance HIV strains have recently been reported （Wensing et al., 2017）. Therefore, it is important to develop new therapies to eliminate HIV in the patients. Immortalized cell lines representing the major targets of HIV in human are important for HIV research and therapeutic development.展开更多
