Robotics research led by Professor Huosheng Hu has
been selected and featured in
EXPO21XX's international online e-Exhibitions.
The EXPO21XX website features several videos of the
robotics research being carried out at Essex and film of the robotic fish in
action at the London Aquarium.
Richard Bartle appeared in the final episode of BBC4's series, The Worlds of
Fantasy on Wednesday 12th March (and its immediate repeat 3 hours later on
Thursday 13th March). He discussed the differences between game worlds and
books. "Every time I read The Lord of the Rings, Sam never pushes Frodo into the
Crack of Doom. Nobody likes Frodo, they'd love to see Sam push him into the
Crack of Doom, but he never does. Why can't Sam, just once, get to push Frodo
into the Crack of Doom?"
The episode "Through the Looking Glass" is no longer
available on BBC iplayer.

GENETIC AND EVOLUTIONARY COMPUTATION CONFERENCE (GECCO-2008) July 12-16,
2008 (Saturday-Wednesday) Atlanta, GA, USA
Two families (stateful and stateless) of genetically programmed classifiers were
tested on a five class brain-computer interface (BCI) data set of raw EEG
signals. The ability of evolved classifiers to discriminate mental tasks from
each other were analysed in terms of accuracy, precision and recall. A model
describing the dynamics of state usage in stateful programs is introduced.
An investigation of relationships between the model attributes and associated
classification results was made. The results show that both stateful and
stateless programs can be successfully evolved for this task, though stateful
programs start from lower fitness and take longer to evolve.

2008 GENETIC AND EVOLUTIONARY
COMPUTATION CONFERENCE (GECCO-2008) July 12-16, 2008 (Saturday-Wednesday)
Atlanta, GA, USA
Single and multi-step time-series predictors were evolved for forecasting
minimum bidding prices in a simulated supply chain management scenario. Evolved
programs were allowed to use primitives that facilitate the statistical analysis
of historical data.
An investigation of the relationships between the use of such primitives and
the induction of both accurate and predictive solutions was made, with the
statistics calculated based on three input data transformation methods:
integral, differential, and rational. Results are presented showing which
features work best for both single-step and multi-step predictions.
