  • Publication number: 20210019250
    Abstract: The present disclosure provides a method, apparatus, device and computer-readable storage medium for guiding symbolic execution. According to embodiments of the present disclosure, it is possible to determine the specific code region of the program, and obtain the program loop output of the program corresponding to the specific code region of the program by using the program inverse analysis method, so that it is possible to obtain the program loop input of the program corresponding to the specific code region by using the program loop predictor according to the program loop output of the program. In this way, the obtained program loop input of the program corresponding to the specific code region may be used to guide the symbolic execution to filter out impossible execution paths and jump out of the program code and reach the specific code region, thereby improving the reliability of the symbolic execution.

  • Patent number: 9434967
    Abstract: The present invention discloses a microbial culture medium and a cultural method. The culture medium comprises a combination of strong acid-weak alkali salts and strong alkali-weak acid salts so that pH value thereof can be regulated and controlled in a stable and suitable range by itself, thus decreasing or eliminating an operable regulation on pH value via an external device in fermentation process and a risk of contaminations resulted from it in fermentation process as well, accordingly greatly improving the controllability and stability of the fermentation process. Meanwhile the ammonium salts acting as strong acid-weak alkali salts can be used as a nitrogen source to replace yeast cream to realize a decreased amount of nitrogen resource of high price, therefor sharply reducing the cost of the culture medium.
