Problem Detail: I am not clear on whether it’s data and control hazards, or control hazards only. Also, the “solved” word confuses me – technically, instruction reordering is used to solve dependences and thus prevent hazards from happening in the first Read More …

[Solved]: k-armed bandit – index policies vs. Q-learning
Problem Detail: I am interested in the stateless k-armed bandit problem, where an agent repeatedly chooses one of k independent arms, each with a different distribution of rewards, and tries to maximize its total reward. I read many papers about this Read More …
[Solved]: Formal language without grammar
Problem Detail: Definitions: Alphabet $Σ$: finite, non-empty set Language: subset of $Σ^*$ Grammar: Unrestricted grammar (Chomsky Type 0) Language of a grammar: all words that can be produced by applying $P$ multiple times, starting from $S$ Grammars are finite, therefore there Read More …
[Solved]: Pumping lemma for a finite language
Problem Detail: Possible Duplicate: Pumping lemma for simple finite regular languages The pumping lemma says that for any regular language $L$, there exists a constant $p$ such that any word $w$ in $L$ with length at least $p$ can be Read More …
[Solved]: Equivalence of GFp and Gp in LTL
Problem Detail: In linear time logic, is $mathbf{GF}p$ equivalent to $ mathbf{G}p$ ? $mathbf{GF}p$ means that it is always the case that p is true eventually. Let $mathbf{G} p$ be defined as: $forall j ge0, p$ holds in the suffix $q_j, Read More …
[Solved]: Pumping Lemma for regular languages proof doubt – Sipser Book
Problem Detail: I was reading the proof of pumping lemma from Sipser’s book. I couldn’t understand certain things mentioned there. In the second paragraph he has written, “because $r_l$ occurs among first $p+1$ places, we have $l le p+1$”. Here, does Read More …
[Solved]: Lovasz theta of even cycle
Problem Detail: How does one show Lovasz theta of even $n$-cycle ($n$ is even) is of form $frac{n}{2}$? Why is the Lovasz theta of such cycles not of form $frac{n cos(frac{pi}{n})}{1+cos(frac{pi}{n})}$. Could someone provide a derivation for even cycle Lovasz theta Read More …
[Solved]: What is the difference between a module in a monolithic kernel and a server in a microkernel?
Problem Detail: I´m not exactly sure what kind of impact these two things have on kernel design. Are servers more flexible because of running in user space, for instance, and does adding a module require a new build of a kernel? Read More …
[Solved]: A Black Box Algorithm
Problem Detail: I’m taking an introductory quantum computations class and I am attempting to solve the following question(s), but we haven’t touched on black box algorithms like this in class, and I honestly don’t know how to solve the question at Read More …
[Solved]: What do I need to know about algorithms?
Problem Detail: Drawing from Are algorithms (and efficiency in general) getting less important?, I get that algorithms are more important than ever, but I need to know anything about them other than their complexities? I would expect to use algorithms out Read More …
