I tried running the science collection examples in 3.99. Most of the plots were just empty, so I need to see if it's a problem with the PLoT package or with my code. [They didn't error, just gave empty plots.] For the ones that did run and which are computationally intensive (with flonums) - like Chebyshev evaluation and (especially) the ordinary differential equation solvers - they 'seemed' much faster. But, it's anecdotal - I just eyeballed it. I have to track down my uses of set-cdr!, etc in the simulation collection before I try any of my larger examples there.
<br><br>One interesting problem came up. Has the use of subcollections in PLaneT changed with 3.99? For example, (require (planet "bernoulli.ss" ("williams" "science.plt") "random-distributions")) says it can't find the file, but it works fine in V372 (and before).

Joyous day! Should my code run in 3.99 I'll do some benchmarking.<br><font color="#888888"><br>N.<br></font><div><div></div><div class="Wj3C7c"><br>On Dec 28, 2007 10:52 PM, Matthew Flatt <<a href="mailto:email@example.com">
