New Blog Post: Some Silly Z3 Scripts I Wrote
2 days ago
- Author resumes website updates after five months, with a new blog post about Z3 scripts.
- The post aims to build hype for the upcoming book 'Logic for Programmers' by publishing independent but related content.
- Discusses 'chaff'—substantial unused material from the book, including code and prose that were cut.
- Struggled to choose a mathematical property for the Z3 example, settling on non-zero a implying existence of b such that b*a=1, avoiding division by zero issues.
- Array example unexpectedly returns 2 instead of the expected 99999999, possibly due to optimization short-circuiting.
- Could not implement an example encoding Goldbach's conjecture due to difficulties with multiple nested quantifiers.
