在本篇論文中,我們考慮了在排列圖上面的嫌惡設施物問題。我們先對於一般圖提出一個k-穩定的性質。之後在排列圖上我們將其分成九類,並證明某些種類的排列圖
分別有4-穩定,3-穩定,2-穩定的性質。最後對於那些滿足4-穩定的排列圖提出$O(n^4)$的演算法、滿足3-穩定的排列圖提出$O(n^3)$、滿足2-穩定的排列圖提出$O(n^2)$的演算法來解決嫌惡設施物問題。
In this thesis, we are concerned with the p-maxian problem in
permutation graphs. At first, we propose the concept of k-stable for
general graphs. We partition all permutation graphs into nine
classes, and prove that it is 4-stable for permutation graphs in
class 1, 3-stable in classes 2, 4 and 2-stable in class 5. Finally,
we propose algorithms for solving the p-maxian problem in
permutation graphs in class 1, permutation graphs in classes 2 and 4
and permutation graphs in class 5 in $O(n^4)$, $O(n^3)$ and $O(n^2)$
time, respectively.
