Outline of Final Research Achievements

In this project, between 2014 and 2017, we investigated the optimal parameters with respect to replica-exchange molecular dynamics method and simulated-tempering method, which are important for biomolecular simulation. In both methods, it is necessary to perform molecular dynamics simulation at a temperature higher than the temperature at which we want to examine actually. However, such high temperature molecular dynamics simulation is unstable. As a method to eliminate this problem, a mass-scaling method has been developed.
