Reference Request: complexity results on finding $(1+\epsilon) \log n$ size clique in $G(n,1/2)$ I am trying to find results on the best known time complexity for finding $(1+\epsilon) \log n$ sized cliques in $G(n,1/2)$. More general results would be great, i.e. if $C_p$ is the constant such that the obvious greedy algorithm finds a clique of size $C_p \log n$ in $G(n,p)$ almost surely, then any results on finding a clique of size $(C_p + \epsilon ) \log n$ would be even better.

In particular, I am interested in whether we know how to find a $(C_p +\epsilon)\log n$ clique in $G(n,p)$ using $O(n^{\epsilon^2\log n})$ time and $O(n^{\epsilon^2\log n})$  space. Would a randomized algorithm that finds a $(C_p +\epsilon)\log n$ vertex clique with high probability under these time and space constraints constitute a publishable result? Any pointers to relevant literature would be greatly appreciated.
To answer the first part of your question, a conjecture in Karp'76 states that there is no efficient algorithm to find cliques of size $(1+ \epsilon)\log(n)$ for $G(n, 1/2)$. This conjecture is still open.
