Lots of numerical methods have parameters (i.e. tolerance, momentum …). While we would want to optimize the parameters and not use the default values (i.e. in 322 project), it is often very difficult to optimize them.
In general, what people do is prepare a test set, run your numerical methods with different parameter values, […]

Working on the projects, you must have had complained about the long running time of your Matlab code when you do a computation on huge matrices. Why do larger matrices take much longer running time? One of the obvious reasons is because there are more numbers to calculate with. If you are a very […]

As it was discussed in a previous blog post, “Moore’s Law, the perfect extrapolation or coming to an end?” written by stri, we are now confronting difficulties with doubling the transistor desnity and computing power. Thanks to engineers’ effort, we have seen the transistor density double every two years and processing speed improve exponentially […]
