90+91

See 90+91 notes and edits for.. notes and edits of each image. 

Re-Ordered

I’ve re-ordered the set because I didn’t feel like the last image (previously the 4th image) fit with the rest of the set.  I also swapped the position of the 2nd and 3rd images. 

It’s 90×90 Plus 91×91

My program went through the full process for both board sizes – starting with 12,000 levels and generating images for the top 60.  

It wasn’t my plan initially to combine the two sets – but I couldn’t see a great set from the 90×90 images, and the first 91×91 images were ready to look at just 3 days after I saw my first 90×90 image.  Two of the five images are from the 90×90 levels, with the other three are 91×91.  

Some Odd Numbers

  • My program generated the 91×91 levels a lot faster than it did the 90×90 levels – between 25 and 40% faster depending on the settings I used to generate the levels.
    • Don’t ask me why – it was a surprise to me.  90×90 (not 91×91) appears to be the outlier though – I was expecting the levels to generate a lot faster than they did.
  • 4 out of the 12000 90×90 levels were generated with a different line algorithm than the rest.  This was a mistake – the algorithm is really bad.  
    • I caught this during the ~8 hour similarity filtering phase when I saw that the top 4 ranked levels had consecutive grid IDs.  
      • they scored really highly because they were different (in a bad way) from the rest of the levels.  
    • Three of the four levels made the original set of 60 levels (I replaced them before imaging). 
      • The 4th level made it into the final 100 levels but finished 99th/100.
      • The level had the misfortune of being paired with one of the other 3 levels for 2 consecutive rounds after being ranked 2nd with 200 levels remaining. 
      • The 4 levels score really poorly against each other – the max score portion of the sim filter formula penalizes them severely for this when paired together.  

91×91 Restored My Interest After 90×90 Nearly Took It Away

After I made the 80×80 Remake I was really looking forward to the 90×90 levels (120×120 suffered as a result).  I was really disappointed.  

I wasn’t expecting 91×91 to be much better – and to be completely honest, my evaluation would shift dramatically if not for two of the levels.  These two levels were exactly what I was hoping for after working on the remake – a really good, new simple pattern, and a really good, new complex pattern.  More info on the notes page

This Time, I Really Believe It

I think this is the best set of 5 images of any set to date.  Not only are all of the images really good individually, they also work very well together as a set (in my opinion).  There is a lot of variety in both the patterns and the colors used for each image.  

I Might Eat My Words

Of course, this isn’t the first time I’ve thought the latest set is the greatest thing since sliced bread – and my evaluation usually changes down the road.  A perfect example is the set closest to this one in terms of board size.  I thought 95×85 was so good, that I included 60 images for the set.  In retrospect, it’s probably my least favorite set since before the original 80×80 set.  That even includes the 111×99 disaster, which I at least find interesting for it’s uniquely uninteresting patterns.
