I think to encourage new idea, we have to introduce some 
generality index to be included in the overall score. When 
a new algorithm is submitted, even it may not be able to 
compete with current best code, but if it shows some 
advantage in generality, it might be pick up by someone 
else to tweak it into top. The generality index can come 
from another hidden testsuit or simply an average results 
by dropping different portion of cases in the testsuite 
(something like cross validation).

Another suggestion, can we make the last 30 minutes or so 
as the twilight phase, or disable downloading an entry from 
the waiting queue? This will encourage people to submit 
their final code earlier.

The node index and 1000 node contest were good. But, it 
seems that the weight of the node index was too small, no 
one cared about it.
