A clustering apparatus includes: an accepting unit that accepts pieces of target data, each of which is a vector; a slime mold information constructing unit that constructs, using the pieces of target data, slime mold information, which is information having one piece of hub cell information corresponding to a central cell of a slime mold and one or more pieces of branch cell information corresponding to a cell that is divided from the central cell for predation; and a clustering unit that associates each of the pieces of target data with branch cell information having the shortest distance from a vector contained in the branch cell information to the target data, among the one or more pieces of branch cell information contained in the constructed slime mold information, thereby clustering the target data into clusters in the same number as that of the pieces of branch cell information.

A high-strength cable having a twisted layer of non-metallic reinforcing elements in outer coatings is disclosed. The reinforcing elements include coating elements, fiber elements of copolyparaphenylene-3,4'-oxydiphenyleneterephthalic amide disposed in the coating elements, and filling materials filled between the fiber elements, respectively. The lateral compression stress of the fiber elements of the copolyparaphenylene-3,4&#x2032;-oxydiphenyleneterephthalic amide is 75 cN/dtex or more.
