Hi, doesn't proper Micromouse rules specify standard maze size of 16 x 16 squares? This was so you could use two bytes to be a "row" and you only need 32 bytes total for all 16x16 squares?? Even if this is a very big maze it would be 32x32, so you can use 4 bytes per row. These competitions are designed by uni computer professors and it seems unlikely they would go for 33x33??? Just doesn't seem right. I have an official micromouse rules sheet and it is 16x16 maze.:o) -Roman -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
