The document describes a simulated car racing competition held over three conferences in 2011. Nine races took place using the TORCS racing simulator. Drivers were developed by various teams and evaluated based on their performance in warm-up, qualifying, and actual races across three tracks. In qualifying, the top performers were AUTOPIA, Mr. Racer, and Powaah. In the final races, Mr. Racer had the highest overall score to win the 2011 championship. The competition provided an exciting and challenging simulated racing environment to evaluate and compare different approaches to developing autonomous racing agents.
The document describes a car racing competition using the TORCS simulator. Competitors submitted controllers trained with neuroevolution techniques like NEAT to race in TORCS. The top performers were Luigi Cardamone's NEAT-evolved controller and Redjava's sensor-based controller. Luigi's controller won by being more reliable, avoiding crashes, while Redjava's was very fast but unstable. The competition showed progress in learning controllers that outperform hand-coded ones, but more work is still needed on cooperation and obstacle avoidance.

The goal was to evaluate vibration properties of the bridge and test sensor technology for structural health monitoring.
This document describes an experimental and numerical study of a steel bridge model through vibration testing. In the experiment, ambient excitation from a moving car model was used to excite the steel bridge model. Accelerometers measured the vibration response, and data was acquired using a LabVIEW program. Ten natural frequencies between 28-166 Hz were identified from the experimental data. Finite element analysis of the steel bridge model in ANSYS found similar natural frequencies and mode shapes to the experiment. The results demonstrate that vibration testing can effectively evaluate the dynamic properties of structures.

Dive into the realm of operating systems (OS) with Pravash Chandra Das, a seasoned Digital Forensic Analyst, as your guide. 🚀 This comprehensive presentation illuminates the core concepts, types, and evolution of OS, essential for understanding modern computing landscapes.
Beginning with the foundational definition, Das clarifies the pivotal role of OS as system software orchestrating hardware resources, software applications, and user interactions. Through succinct descriptions, he delineates the diverse types of OS, from single-user, single-task environments like early MS-DOS iterations, to multi-user, multi-tasking systems exemplified by modern Linux distributions.
Crucial components like the kernel and shell are dissected, highlighting their indispensable functions in resource management and user interface interaction. Das elucidates how the kernel acts as the central nervous system, orchestrating process scheduling, memory allocation, and device management. Meanwhile, the shell serves as the gateway for user commands, bridging the gap between human input and machine execution. 💻
The narrative then shifts to a captivating exploration of prominent desktop OSs, Windows, macOS, and Linux. Windows, with its globally ubiquitous presence and user-friendly interface, emerges as a cornerstone in personal computing history. macOS, lauded for its sleek design and seamless integration with Apple's ecosystem, stands as a beacon of stability and creativity. Linux, an open-source marvel, offers unparalleled flexibility and security, revolutionizing the computing landscape. 🖥️
Moving to the realm of mobile devices, Das unravels the dominance of Android and iOS. Android's open-source ethos fosters a vibrant ecosystem of customization and innovation, while iOS boasts a seamless user experience and robust security infrastructure. Meanwhile, discontinued platforms like Symbian and Palm OS evoke nostalgia for their pioneering roles in the smartphone revolution.
The journey concludes with a reflection on the ever-evolving landscape of OS, underscored by the emergence of real-time operating systems (RTOS) and the persistent quest for innovation and efficiency. As technology continues to shape our world, understanding the foundations and evolution of operating systems remains paramount. Join Pravash Chandra Das on this illuminating journey through the heart of computing. 🌟

more similar to a real-world problem
• Proposing a funny and exciting competition
you can watch or play with the entries of the
competition
human players can interact with AI
a lot of programmed AI available for comparison
• Proposing a challenging competition
computationally expensive
real-time
on-line learning
noisy sensors

IEEE CIG-2011 August 31 – September 3 - Seoul, Korea
6. Sensors and actuators 6
• Rangefinders for edges on the track and opponents
(with Gaussian noise)
• Speed, RPM, fuel, damage, angle with track, distance
race, position on track, etc.
IEEE CIG-2011 August 31 – September 3 - Seoul, Korea
7. What is the structure of a race?
Three stages: warm up, qualifiers, actual race
During warm-up, each driver can explore the
track and learn something useful
During qualifiers, each driver races alone against
the clock (the best 8 drivers move to the race)
During the race all the drivers race together
IEEE CIG-2011 August 31 – September 3 - Seoul, Korea

10. Mr. Racer 2011 10
• 13 Variables learned offline with the CMA-ES
• Warmup used to learn a model
of the track
• Noise Handling:
Low pass filter on sensor values
2 Regression polynoms are fitted to each side
Resample the polygons
• Overtaking
Computes on the fly a recommended
speed and an overtaking line
Recommendation are provided to a planing module
IEEE CIG-2011 August 31 – September 3 - Seoul, Korea
12. Mariscal & Fernández 12
• Expert system improved by multi-objectives evolution
Maximize distance.
Minimize damage
• Steering based on a simple rule
follow the track sensor returning
the biggest distance
• Overtaking based on simple rules and expert systems
IEEE CIG-2011 August 31 – September 3 - Seoul, Korea
14. Ready2Win 14
• Modular architecture:
The driving module compute speed
using the maximum braking distance
Overtaking module
Recovery module
ABS module
• Track learning during the warm-up:
First lap, driven slow, to identify turns (start, end, entry
position, curvature) and learn the track model
In the other laps, adapt speed: increase it according to
lateral speed, reduce it when the car goes off-road
IEEE CIG-2011 August 31 – September 3 - Seoul, Korea
16. Powaah 16
• Based on Artificial Potential Field
• Every sensor in the span (-40, +40) has a charge
• The charge is based on how far the sensor measures the
track
• Coulomb’s law is used to calculate potentials in the field
Pot = (C1 * C2 ) / d2
• The sensor with the highest potential is used for
computing how much steering is needed
IEEE CIG-2011 August 31 – September 3 - Seoul, Korea
18. Ho Duc Thang 18
• Hybrid fuzzy controller with a module to learn the model
track as the car drives, a module to perform some simple
plannings based on the modelled segments of the track
and a fuzzy controller which actually drives the car.
• All the modelling, planning and driving are done during the
race, the warm-up stage is not exploited
• No opponent handling

19. CRABCAR

and Magnus Westergaard,
IEEE CIG-2011 August 31 – September 3 - Seoul, Korea NTNU
20. CRABCAR 20
• Turns classification based
on sensors during warmup
and saved in the track
model
• Different evolved strategies
to go through the turns
• Strategies are re-evaluated
during stages, adjusted
and save in the track
model
• Simple opponent
avoidance based on
keeping safe distance
IEEE CIG-2011 August 31 – September 3 - Seoul, Korea
22. BFB3 22
• Scripted approach for steering and accelerating
• Jump Detection
When the Z-Sensor is more than 0.4
While the car is jumping and landing (few times, 10 tick
count), the steer of car is fixed to forward
• Opponent avoidance:
Just brake if the opponent is approached on a straight
Modify the normal steering when the opponent is
approached in a bend

24. AUTOPIA 24
• Fuzzy Architecture based on three basic modules for
gear, steering and speed control optimized by a genetic
algorithm
• Learning in the warm-up stage:
Keep a real vector with as many values as track length
Vector initialized to 1.0
If the vehicle goes out of the track or suffers damage
then multiply vector positions from 250 meters before
the current position by 0.95.
• During the race the vector is multiplied by F to make the
driver more cautious in function of the damage:
F=1-0.02*round(damage/1000)

Generated through interactive evolutionary
computation
http://trackgen.pierlucalanzi.net

• Each controller raced for 100000 game ticks in the warm-
up stage and then its performance is computed in the
qualifying stage as the distance covered within 10000
game ticks
