Throughout, we denote by SOL(Λ,a,Θ,b,K)the solution set of GPCP(Λ,a,Θ,b,K) for notational convenience. Theorem 3.1.

WebA set S is called compact if, whenever it is covered by a collection of open sets { G }, S is also covered by a finite sub-collection { H } of { G }. Question: Does { H } need to be a proper subset of { G }? If, for instance, { G } is already a finite collection, does that mean S is automatically covered by a finite sub-collection of { G }?

"WebCompactness or cluster cohesion: Measures how close are the objects within the same cluster. A lower within-cluster variation is an indicator of a good compactness (i.e., a good clustering). The different indices for evaluating the compactness of clusters are base on distance measures such as the cluster-wise within average/median distances between … " - Set compactness
