To add to this. The first DARPA Grand Challenge was held a little more than 18 months ago. At that time no one completed the race. CMU's Sandstorm went about 7 miles and then crashed out of the challenge. None of the others even came up to 7 miles.

I was working under one of the CMU Prof's who also happened to be one of the external technical advisor for Sandstorm. The reason he gave for the crash was the technical people behind Sandstorm did not forsee the following situation: Encounter a curved uphill slope.

So apparently Sandstorm did not reduce its speed when it encountered the curved uphill slope. Hence it jumped the tracks, which lead it to crash and eventually one of the wheels caught fire.

NAME

       WWW::Search::Yahoo::News::Advanced - search Yahoo!News using the "advanced" interface

SYNOPSIS

	 use WWW::Search;
	 my $oSearch = new WWW::Search('Yahoo::News::Advanced');
	 my $sQuery = WWW::Search::escape_query("George Lucas");
	 $oSearch->date_from('7 days ago');
	 $oSearch->date_to  ('now');
	 $oSearch->native_query($sQuery);
	 while (my $oResult = $oSearch->next_result())
	   print $oResult->url, "
";

DESCRIPTION

       This class is a Yahoo! News specialization of WWW::Search.  It handles making and interpreting searches on Yahoo! News
       http://news.yahoo.com using the Advanced search interface.

       This class exports no public interface; all interaction should be done through WWW::Search objects.

NOTES

       This backend supports narrowing the search by date-range.  Use date_from() and date_to() to set the endpoints of the desired date range.
       You can use any date format supported by the Date::Manip module.

       NOTE that Yahoo only seems to keep the last 60 days worth of news in its searchable index.

       At one time, News.yahoo.com would die if the unescaped query is longer than 485 characters or so.  This backend does NOT check for that.

SEE ALSO

       To make new back-ends, see WWW::Search.
