I was in Las Vegas for a convention from 3/3 to 3/7. The conference was held in RIVIERA casino & hotel. I was pretty lucky to present my paper on 3/4, the sencond day of conference. Thus, I could relax myself to enjoy the rest of meeting and, of course, play couple hands of game without too much stress. I have been Las Vegas three times, so basically I am familiar with the city of sin. I didn't go to those luxurious casino and hotel on the Las Vegas Strip because I visited them three years ago. It is really a good experience to attend conference. I believe I have got some idea for my next research project.
