A basis of an LP-type problem is a set B ⊆ S with the property that every proper subset of B has a smaller value of f than B itself, and the dimension (or combinatorial dimension) of an LP-type problem is defined to be the maximum cardinality of a basis.
In the weighted set cover problem, each set is assigned a positive weight (representing its cost), and the goal is to find a set cover with a smallest weight. The usual (unweighted) set cover corresponds to all sets having a weight of 1.
Atlantic horseshoe crab Limulus polyphemus. Limulus amebocyte lysate (LAL) is an aqueous extract of motile blood cells from the Atlantic horseshoe crab Limulus polyphemus.LAL reacts with bacterial endotoxins such as lipopolysaccharides (LPS), which are components of the bacterial capsule, the outermost membrane of cell envelope of gram-negative bacteria.
For example, the LP relaxations of the set packing problem, the independent set problem, and the matching problem are packing LPs. The LP relaxations of the set cover problem, the vertex cover problem, and the dominating set problem are also covering LPs. Finding a fractional coloring of a graph is another example of a covering LP.

Scientific literacy may also be defined in language similar to the definitions of ocean literacy, [4] Earth science literacy [5] and climate literacy. [6] Thus a scientifically literate person can: Understand the science relevant to environmental and social issues. Communicate clearly about the science. Make informed decisions about these issues.
[4] The amount of process-initiating Gibbs free energy in a deformed metal is also reduced by the annealing process. In practice and industry, this reduction of Gibbs free energy is termed stress relief. [citation needed] The relief of internal stresses is a thermodynamically spontaneous process; however, at room temperatures, it is a very slow ...
