assignment problem

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 ..

Trigonometry is a fascinating tool, initially conceived from chords in a Unit-Circle it has wide applications and whenever space is involved Trigonometry is used irrespective of the area of interest. Trigonometry involves the study of concepts like the Sine, Cosine, Tangent and Cotangent. Get best..

If two or more structures can be assigned to a molecule, none of which is capable of describing all the known properties of the compound, then the actual structure is known to be a resonance hybrid or an intermediate of these structures. The various structures written are called res..

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 de..

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 ..

For high fidelity reception, the audio frequencies from 20Hz to 20000Hz must be reproduced. This requires a bandwidth + 20000Hz i.e., 40000Hz. (Note that both the sidebands must be reproduced). The bandwidth actually assigned for AM transmission is 20000Hz. This is done to keep the inter..

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..

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...
