Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Some new algorithm developments on highly stiff stable schemes and on a SAV based approach for optimization problems
高刚性稳定方案 基于SAV 优化方法 新算法发展
2023/11/29
In the first part, I shall present a new way to construct highly stiff stable schemes. Traditional time discretization schemes are usually based on Taylor expansions at $t_{n+\beta}$ with $\beta\in [0...

2017年物联网的实现会议（Actualization of the Internet of Things: Physicists Return to Address the Problems of the Internet That They Created）
2017年 物联网的实现 会议
2017/3/30
The Internet was invented by physicists, emerging from scientists at CERN who needed a means to send information quickly to geographically dispersed team members. The systems that have evolved since t...
Computers have proven capable of helping scientists solve many research problems, from the dynamics of black hole mergers to distant connections in reams of genomic data.But there are some problems th...
Fitness:Philosophical Problems
environment evolution fitness drift measurement natural selection propensity interpretation tautology
2016/6/15
Fitness plays many roles throughout evolutionary theory, from a measure of populations in the wild to a central element in abstract theoretical presentations of natural selection. It has thus been the...
