Proth Weight Applet information

This applet computes a "Proth Weight" for each Proth coefficient k. The computed weight indicates the asymptotic expected density of primes of the form k*2^n+1. The weight is normalized to the prime number theorem; a coefficient with a weight of 1.00 would have the same density of primes as a randomly chosen set of odd numbers of the same magnitude.

The best and worst weight to k ratios (w/k) computed are displayed for your use. Note that if the weight is computed as 0, the number is very likely a Sierpinski number.

You should be able to figure out the applet's use easily; however, there may be bugs. If you find any bugs, report them and I'll try to fix...

If you get a Java error during loading of the applet, such as a security violation or a message about a missing class or method, your browser probably does not support the Java AWT version 1.1; try upgrading to the latest version of your browser.

The source code to the applet is here. I make no claims about the quality of code.

Please send any feedback to Mini-Geek (modified the code; see Small Request for Proth Numbers) or to its original creator jack@brennen.net (see also original app)
