Comparison With Other PRNGs
If higher quality random numbers are needed, and sufficient memory is available (~ 2 kilobytes), then the Mersenne twister algorithm provides a vastly longer period (219937 − 1) and variate uniformity. The Mersenne twister generates higher-quality deviates than almost any LCG. A common Mersenne twister implementation, interestingly enough, uses an LCG to generate seed data.
A Linear Feedback Shift Register PRNG can be implemented with essentially the same amount of memory and produces a stream of pseudorandom numbers with better randomness qualities when considering streams of bits, albeit with a bit more computation.

Famous quotes containing the words comparison with and/or comparison:
“What is man in nature? A nothing in comparison with the infinite, an all in comparison with the nothing—a mean between nothing and everything.”
—Blaise Pascal (1623–1662)
“Away with the cant of “Measures, not men!”Mthe idle supposition that it is the harness and not the horses that draw the chariot along. No, Sir, if the comparison must be made, if the distinction must be taken, men are everything, measures comparatively nothing.”
—George Canning (1770–1827)
