Witryna26 paź 2006 · Using this result, and combinatorial geometry results implying bounding functions f (c) that are nearly linear, we obtain o (log c) approximation algorithms for covering by fat triangles, by pseudo-disks, by a family of fat objects, and others. Similarly, constant-factor approximations follow for similar-sized fat triangles and fat objects, … Witryna4 gru 2024 · We set the value of \alpha by using Theorem 1 which provides the best approximation guarantees. The value of \epsilon ' is set to several times higher than \epsilon to reduce the complexity but still ensure approximation ratios. The detail of our algorithm is presented in Algorithm 2. Lemma 2
