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.

an opening or hiatus. anion gap the concentration of plasma anions not routinely measured by laboratory screening, accounting for the difference between the routinely measured anions and cations and equal to the plasma sodium â (chloride + bicarbonate); used in the evaluation of acid-base disorders.
