definition of assignment problems

There are mainly four steps in the mathematical formulation of linear programming problem as a mathematical model. We will discuss formulation of those problems which involve only two variables. Identify the decision variables and assign symbols x and y to them. These ..

The oxides of halogens are acidic while hydrogen oxide (H 2 O) is neutral. Cl 2 O : H 2 O Acidic Neutral From the above discussion, it is clear that hydrogen is unique in its behaviour because it resembles alkali metals as well as the halogens. Therefore, it is difficult to assign any ..

Nomenclature of Carbon Compounds - "Nomenclature is the system of assigning a proper name to a particular carbon compound on the basis of certain rules." Most of the carbon compounds have two types of names: Trivial Names IUPAC Nam..

The arrangement of atoms that is characteristic of a particular stereoisomer is called its configuration. For e.g., for lactic acid, there are two stereoisomers. One rotates the plane of polarized light to the right and is named dextro or (+) lactic acid. The other stereo isomer rotates the plane ..

Constants and variables Symbols having fixed values are called constants. Examples: 5, π, ¾, 1.5. Symbols which can be assigned with various numerical values are called variables or literals. Examples : x, y, y 2 . In the formula for circumference of a circle, c=2π..

Priorities are assigned to the four different groups or atoms attached to the chiral carbon atom. One such rule is based on atomic numbers. An atom with higher atomic number gets higher priority. Foe e.g., in bromochloroiodomethane the sequence of priority is iodine, bromine, chlorine an..

Let S be a sample space associated with a given random experiment. A real valued function X which assigns to each w i S, a unique real number...

Ozone is an allotropic form of oxygen. Its molecular formula is O 3 and molar mass is 48 g mol - 1 . Schonbein (1840) concluded that Van Marums observations in 1785 of a peculiar smell, when an electric discharge was passed through oxygen (or air), was in fact a new gas. He named it Ozone, which is..
