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.

Anion (or negative ion) are atoms or molecules having more electrons than protons and giving off what is called as a negative charge. In nature, negative ions (anions) are created from air molecules, radiation, broken apart from sunlight, and moving air or moving water.
