For many natural P-complete graph problems, where the graph is expressed in a natural representation such as an adjacency matrix, solving the same problem on a succinct circuit representation is EXPTIME-complete, because the input is exponentially smaller ; but this requires nontrivial proof, since succinct circuits can only describe a subclass of graphs.

) Further, in languages like C ++, where subclasses can be compiled separately from superclasses, a change to a superclass can actually break precompiled subclass methods.

Ammonites ( subclass Ammonoidea ) can be distinguished by their septa, the dividing walls that separate the chambers in the phragmocone, by the nature of their sutures where the septa joint the outer shell wall, and in general by their siphuncles.

An important subclass of Kac – Moody algebras corresponds to symmetrizable generalized Cartan matrices C, which can be decomposed as DS, where D is a diagonal matrix with positive integer entries and S is a symmetric matrix.

In addition, there are a number of cases where conversions led to complete reclassification, where similar circumstances later would be indicated simply by allocating a new subclass.

In bee or wasp venom immunotherapy, immunoglobulin subclass IgG4 has been considered to be particularly important, where IL-10 make the B cells to switch the produced immunoglobulin class from IgE to IgG4.

Micas are also T-O-T-stacked phyllosilicates, but differ from the other T-O-T and T-O-stacked subclass members in that they incorporate aluminium into the tetrahedral sheets ( clay minerals have Al < sup3 +</ sup > in octahedral sites ).

Several rock-forming minerals are part of this subclass, such as the aluminosilicates, the olivine group, and the garnet group.

An important subclass are the local search methods, that view the elements of the search space as the vertices of a graph, with edges defined by a set of heuristics applicable to the case ; and scan the space by moving from item to item along the edges, for example according to the steepest descent or best-first criterion, or in a stochastic search.

An important and extensively studied subclass are the graph algorithms, in particular graph traversal algorithms, for finding specific sub-structures in a given graph — such as subgraphs, paths, circuits, and so on.

Another important subclass of this category are the string searching algorithms, that search for patterns within strings.
