Key Points

A user asks about issues on OpenReview when inserting long LaTeX/TeX code, noting that the Markdown/TeX compilation appears to stop working with lengthy expressions.
The reporter shares an example where a displayed formula renders correctly when split into smaller pieces (one item per line), but fails when written as a long continuous LaTeX block.
The question includes specific LaTeX equations (two expected-value formulas) to illustrate how the formatting affects whether OpenReview successfully compiles the content.
The discussion is framed as troubleshooting editor/formatting limits or parsing behavior in OpenReview’s Markdown/LaTeX pipeline rather than as a new AI method or research result.

Hi, has anyone had issues with Open Review when you try to add long tex code? The markdown just stops compiling?

For example, I want to write a formula like this:

It gets displayed like this:

But when I broke the formula into small pieces, like 1 item per line, it worked.

The LaTeX code is as follows:

$$ \mathbb E\left[\left(\widehat q^{DSI}_{\alpha,S,N}-q^\star\right)^2\right] = \frac{1}{f^\star(q^\star)^2} \left(b_q^2+\frac{\sigma_q^2}{K_{\mathrm{eff},q}}\right) +L^{sam}_{q,N}+o(\cdot), $$ and $$ \mathbb E\left[\left(\widehat{ES}^{DSI}_{\alpha,S,N}-ES_\alpha(P^\star)\right)^2\right] = \frac{1}{\alpha^2} \left(b_{ES}^2+\frac{\sigma_{ES}^2}{K_{\mathrm{eff},ES}}\right) +L^{sam}_{ES,N}+o(\cdot). $$ ```
