Assignment 4: Effects: Control and Storage 15-312: Principles of Programming Languages (Fall 2023) This assignment will familiarize you with effects that are widely present in programming language. Effects, or side effects are umbrella terms used to describe any computational phenomenon that is not fully captured in the return value of an expression. Common examples of
Bloom Filters Project Due: Tuesday, November 22 (by 11:59pm), via Gradescope In this assignment you will implement a Bloom filter and then analyze the false positive rate that your implementation achieves versus the theoretical claim. You need to turn in a PDF report. Your grade will depend partially on the quality of your report. This

CS 3MI3: Fundamentals of Programming Languages Due on Friday, November 10th at 11:59pm EST Dr. Jacques Carette The goals of this assignment are: 1. Learn how to interpret small-step semantics 2. Learn how to translate semantics into an implementation 3. Learn how to identify buggy semantics A project template is available on the course GitHub
For most languages, types are not needed at run-time. Consider this type erasure function. erase(x) erase(λx : T1.t2) erase(t1 t2) = λx.erase(t2) = erase(t1) erase(t2) By careful design, we have: t → t′ =⇒ erase(t) → erase(t′). Proved by induction on evaluation derivations. erase(t)→m′ =⇒ ∃t′ |t →t′ ∧erase(t′)=m′ J. Carette (McMaster University) Types Fall
