Submitting Chrome-8 Update to AppStore

May 4th, 2010

Chrome-8 can now show hints in Master mode. I’ve received many requests for this feature and it is also the only “con” AppSpy found when reviewing Chrome-8.

Now Chrome-8 8.4 is submitted for review, and will normally be released within a few days. Check it out at the AppStore!

So what’s NP-complete anyway?

May 4th, 2010

Since there are so many good sources defining NP-complete (see below) I will just give my “elevator pitch”.

To say that a problem is NP-complete means that there is no known way of efficiently computing answers to the problem in general. There will always be a worst case when the computation will require exponential time to finish. However, given any proposed solution to an NP-complete problem, it is possible to efficiently check whether the solution is correct or not. A popular example is the Traveling Salesman Problem (TSP) which is the problem of computing the cheapest way to visit, say, all major cities in the USA for any given timetable and cost.

Showing that a problem is NP-complete involves finding an efficient translation of the problem into a known NP-complete problem.

There are many problems that are found to be NP-complete, for instance Graph Coloring, the basis for my puzzle Chrome-8.

Here’s a short list of references:

iPhone OS 4

April 8th, 2010

Time to start work on the apps for iPhone OS 4 coming out this June! I need to skip a few maintenance releases of Chrome-8 in order to manage. But I’m sure it’s going to be worth wile.
