Sommario/riassunto |
|
The 5th edition of Model Building in Mathematical Programming discusses the general principles of model building in mathematical programming and demonstrates how they can be applied by using several simplified but practical problems from widely different contexts. Suggested formulations and solutions are given together with some computational experience to give the reader a feel for the computational difficulty of solving that particular type of model. Furthermore, this book illustrates the scope and limitations of mathematical programming, and shows how it can be applied |

Sommario/riassunto |
|
Born into slavery in North Carolina around 1786, Moses Grandy was bequeathed to his young playmate, his original owner's son, when they were both eight years old. Hired out until he was twenty-one, Grandy describes each of his temporary masters-some cruel and some kind. His first wife is sold shortly after they marry, and he never sees her again. After saving his money whenever possible and buying his freedom for 600, Grandy is betrayed by his childhood friend, who sells him. Grandy marries again and purchases his freedom a second time, only to be once again betrayed. With the assistance |
