Robni stražarji v trdnjavskem problemu : delo diplomskega seminarja

Berlič, Primož (author), Škrekovski, Riste (mentor)

V diplomskem seminarju bomo obravnavali trdnjavski problem z robnimi stražarji. Trdnjavski problem je problem, pri katerem je trdnjava predstavljena kot poligon v ravnini, stražarji pa so točke ali robovi v ravnini. Dokazali bomo, da je v splošni trdnjavi $\lceil n/3 \rceil$ robnih stražarjev včasih potrebnih in vedno dovolj, da zastražijo zunanjost trdnjave. Pri ortogonalni trdnjavi pa potrebujemo $\lfloor n/4 \rfloor + 1$ robnih stražarjev.

• Title: Edge guards for the fortress problem

Abstract

In this seminar we consider the fortress problem with edge guards. In the fortress problem the fortress is considered a polygon and guards are points or edges in a plane. We will prove that it is always possible to guard exterior of general fortress with $\lceil n/3 \rceil$ edge guards and exterior of orthogonal fortress with $\lfloor n/4 \rfloor + 1$ edge guards.
