Sure! Some positive ones: 1) Spot-on prediction: PROMPT: lines with 3 or more characters or lower-case letters PRED: ((.)|([a-z])){3,} GOLD: ((.)|([a-z])){3,} 2) Learned to generalize and produced a simpler regex: PROMPT: lines with a character and the string 'dog' PRED: .*(.)&(dog).* GOLD: .*((.)+)&(dog).* 3) Also learned to generalize and produced simpler regex without duplicate logic: PROMPT: lines not containing a letter PRED: .*~(([A-z])+).* GOLD: (.*)(.*~([A-z]).*) 4) Handling multiple references correctly: PROMPT: lines using 'su' after 'sun' or 'soon'. PRED: .*(sun|soon).*su.* GOLD: .*(sun|soon).*su.* Though I find the mistakes interesting as well! 1) Issues counting properly: PROMPT: lines containing a 5 letter word beginning with 't' PRED: .*\bt[A-z]{5}\b.* GOLD: .*\bt[A-z]{4}\b.* 2) Misallocation of parenthesis (to be fair, the prompt is slightly ambiguous): PROMPT: lines with 'dog' follwed by 'truck' and a lower-case PRED: (dog).*((truck)&([a-z])).* GOLD: (dog.*truck.*)&(.*[a-z].*)
