Integer Programming (IP) is a very powerful technique for tackling problems which have a mixture of continuous and discrete activities, notably those involving scheduling. Unlike Linear Programming (LP), IP cannot simply be treated as a black box.
The Anion Gap is an approximate measurement of ions, that is molecules with a charge, either negative or positive. Sodium and potassium are positively charged and therefore called cations; this is why they are often represented as Na+ and K+ respectively.These two are the main cations measured in the blood.he Anion Gap is an approximate measurement of ions, that is molecules with a charge, either negative or positive.

They differ from cations which have a positive charge. In medical terms, the anion gap is the difference between the amount of anions and cations in a person's blood. The anion gap may be high, normal or low. This difference may be caused by diabetes or by a condition known as acidosis.
