On the covering of $n + ε$ square with $n^{2} + 1$ unit squares for $n \geq 4$

Sira Sriswasdi

In 2006, Alexander Soifer conjectured that one cannot fully cover a square of side length $> n$ with $n^{2} + O (1)$ unit squares. For small $n \in {2, 3}$ , in 2009, Janusz Januszew…

Lower Bound for Convex Hull Area and Universal Cover Problems

Tirasan Khandhawit, Dimitrios Pagonakis, Sira Sriswasdi

In this paper, we provide a lower bound for an area of the convex hull of points and a rectangle in a plane. We then apply this estimate to establish a lower bound for a universal…

An Improved Lower Bound for Moser's Worm Problem

Tirasan Khandhawit, Sira Sriswasdi

We show that any convex region which contains a unit segment, an equilateral triangle of sides 1/2, and a square of side 1/3 always has area at least 0.227498. Using grid-search al…
