My Analyzer correctly identified the type for this unknown and my automatic solver solved it correctly without the crib, but I will include a crib in Caesar. The plaintext is a sentence randomly taken from the Internet.

Here’s another unknown. It consists of one sentence taken randomly from gutenberg.org. My program correctly identified the type and my hillclimber solved it. The text omits a year in numerical form.
This was properly identified by my Analyzer, but it took me some work interactively using the crib to solve it. The text consists of two unrelated sentences randomly pulled from Gutenberg.org
Thecrib in Caesar is: PAIOWAPMEZWBMBWUMI
Here is a Quag IV. I had great difficulty solving this, even after using the crib. I think I must have entered data wrong into my key search program, which failed to find the correct keys, resulting in a lot of wasted efforts.
Here’s a cipher of unknown type. My programs deduced the correct type and solved it without a crib, but I will provide a crib. The plaintext consists of two unrelated sentences chosen randomly from Gutenberg.org.

My Analyzer didn’t rank the correct type as possible, but I eventually tried it and my hillclimber solved it.

A new member (Gerard) has just posted a comment on a post from months ago where it will not be seen requesting assistance in solving the cipher below. I’m reposting the text here and will send him a link to this page. If anyone solves it or has suggestions, please post them in the comments here.
Could you help me solve this?

This 2-sentence ciphertext was generated by my random con generator. The text is from gutenberg.org. My program diagnosed it as fractionated Morse and my hill-climber solved it in 1.57 seconds. I’m not going to provide a crib since I think it’s not necessary

This con is a randomly selected sentence from the Internet. My Analyzer placed the correct cipher type in 17th place! My hill-climber solved it without a crib, but I am including a Caesar-shifted crib: HUKOVWL. Correction: The first sentence was too short, so my program selected the beginning of another sentence to lengthen it. The second sentence is truncated in the middle of a word.
