In Shakespeare's The Merchant of Venice, Portia vetted her suitors by asking them to uncover which of three caskets concealed her portrait, while inscriptions on the caskets presented riddles that tested the virtue of her potential partners. In the classic What is the Name of this Book? logician Raymond Smullyan imagined several generations of clever Portias presenting suitors with caskets inscribed with statements that together formed a logic puzzles whose solution would lead to the portrait. Our Portias are friendly algorithms that spend their time generating logic puzzles for your enjoyment; no offers of marriage are on the table.
