Komlos conjecture is about the existing of a universal constant $K$ such that for all dimension $n$ and any collection of vectors $\overrightarrow{V_1},\dots ,\overrightarrow{V_n}\in {ℝ}^n$ with $\overrightarrow{V_{.}}{}_2\le 1$ , there are weights ${\epsilon }_i\in \left\{-1,1\right\}$ in such that${\displaystyle \sum }_{i=1}^n$. In this paper, the constant $K\left(n\right)$ is evaluated for $n\le 5$ to be $K\left(2\right)=\sqrt{2}$, $K\left(3\right)=\frac{\sqrt{2}+\sqrt{11}}{3}$, $K\left(4\right)=\sqrt{3}$, and $K\left(5\right)=\frac{4+\sqrt{142}}{9}$. For higher dimension, the function $f\left(n\right)=\sqrt{n-lo{g}_2\left(2^{n-1}/n\right)}$ is found to be the lower bound for the constant $K\left(n\right)$, from where it can be concluded that the Komlos conjecture is false i.e., the universal constant $K$ does not exist because of $\underset{\text{n}\to \infty }{\lim }K\left(n\right)\ge \underset{\text{n}\to \infty }{\lim }\sqrt{\log \left(n\right)-1}=+\infty$.
