Finally, a poset is called rank-unimodal if the sequence of sizes of the ranks is unimodal, increasing up to a widest point in the poset's middle and decreasing thereafter.

2 I recently became interested in this definition in trying to make rigorous my answer to this Question. In the univariate case a notion of unimodal function is generalized from that of a …

May 2, 2020 · Now I wanted to prove that this function is unimodal but I am unable to do so. Actually, I was learning Ternary Search so I wanted to apply that technique to a problem and …

May 4, 2016 · Normal distributions are always unimodal. It looks like by "bimodal normal data" you mean a Gaussian Mixture Model (GMM) with 2 components (i.e. the PDF of the data is a …
