Sea of Yellow

Barke and I had a wonderful time at Jean's, was sure nice of her to let me bring him over and nice of Laverne to drive us. I felt bad that he's home alone all day during the week and didn't want to leave him again on Sat. Jean used to have a German Shepherd and Barke kind of reminds her of him. I ended up winning the day, including playing RA(TI)ONING, a nice 9. In my last round, I bingoed with WANTONER, got a challenge, bingoed again with PRIVATE and then picked up 26 points from the letters on my opponent's rack. Nice way to pull ahead by an extra 200 points.

Made some huge inroads into EII, I've always wanted to do a beam stack search with 100,000 nodes. In english, it means having the computer look at the most promising 100,000 positions before going forward to look at the next ones. In heuristic search, it's common to just look at one idea at a time. With this approach in EII, if you make one bad move early on, you'd have no chance to find the solution. This puts the eggs into 100,000 baskets instead of 1. With a search space of 10^45 and my ability to look at 10^5 at a time, I'm still not holding my breath for the $2 million prize. But with a litmus test of a beam size of 20,000 I was able to find better answers than I have to date. It took it 1 day to run. Now that I have a larger width, 200,000 actually, it should about 10 times as long, so in a week or two I'll see how much farther, if any, it was able to get.

I was able to place 211 / 256 pieces before it determined it would be unsolvable. Not great, but that means all but basically three lines were done.

I could score much higher if I was just counting the matching edges out of 480. But I'm trying to get a full solution, not just a high score for a partial solution.

Fall in Calgary

I hope to post some photos soon!

I had a great walk with Barke down to Kensington tonight. I was going to go to a Schawarma place for dinner but it was too busy and I'd have had no where to sit. So I retraced my steps 3 blocks and ended up on the OJ's patio. Had a great steak sand, two beers, and tied Barke up outside. He snarled at two dogs that went by, he always has that issue when tied up. But otherwise, he made at least 10 new people friends. Everyone always loves him.

Was nice to relax and enjoy one of our last summer evenings, if you can call them that. I had my netbook and did some anagramming. We have our Western Canadian tournament coming up, and it's about 5 days of Scrabble. I've now got three modes for studying words

New Words
Tournament Prep

The new words are just that, new words based on my own priority system. The review is a randomized selection of words that are due to be studied again. The randomization is important so you don't feel you're doing the same ones over and over. And the tournament prep focuses only on the important words I need to know, that are due for review. After years of studying, this seems to be the best breakdown. I'll focus on tournament prep for the WCSC.

I've been obsessing too much about Eternity II lately, but really loving it. Have some new ideas to try out tonight. It's been nice talking to fellow enthusiasts on the yahoo newsgroup lately.

Christine is out in New York, and I've been making the most of my free time - Reading Simple Chess, doing excellent daily and weekly chess problems at and lots of work at EII
Not to mention lots of scrabble study still.

Here's a daily puzzle sample
