Linear programming techniques have proven highly effective for solving problems in various fields of human activity. Of great importance is the use of such methods and tools for solving problems of optimal design, which should take into account a huge number of constraints, due to the large amount of computation. In this regard, students of technical universities, students in field of "Computer Science", to the knowledge of the possible application of mathematical methods and computers, and an understanding of the problems that arise when using them. The developed program set the following tasks: the generation of the initial basic feasible solution; search for the optimal plan and the extreme non-integer linear programming problem; search an optimal plan and extremum fully integer linear programming problem; search for the optimal plan and the extreme part of the integer linear programming problem; source code in Delphi, as the program itself, you can free download on the page. In a number of practical problems into manageable variables except for the restrictions imposed additional conditions, such as integer requirements (eg number of products with the most efficient use of limited resources in economic optimization problems), or the range of possible values of the task (optimizing the distribution of arrays on the levels of computer memory). And quite often it does not affect all the variables, but only some of them. Integrality condition the solution may be provided by the implementation of the method of Gomori. In this case, the search for solutions to the problem of integer programming begins with determine the simplex method an optimal plan without integer variables.continue reading
This text aims to make a first approach to the question "Why should I study Physics? that many students do. It is a personal reflection as a narrated long our ancestors were frightened and amazed by the natural phenomena occurring. These mood changes produced by these phenomena led these men to seek explanations for what happened and try to control nature and that the effects produced were sometimes catastrophic. The first explanation of what happened were surrounded by a religious environment, every phenomenon has become uncontrollable and incomprehensible a God to worship only the constant and systematic slaughter of its periodic could soothe fury. This form of control has been improved to be managed by men to deal with other men. The gods were taking more and more human forms, vengeful, punitive and segregative where only a select few understood the strength of their arguments and only through him could, with some luck, avoid the terrible effects of drift with the freedom of thought.
The senses were controlled by the gods, had given to us they should, therefore everything that was perceived by them was the work of them and there was no wrong choice, the world was what the senses perceive, was the work the creator and there was no room to doubt it. What could not be explained by understanding those with a direct link to the architect of this supreme work. But the man was endowed with thought and this was beyond the senses, imagined, dreamed, analyze, relate, he found new clues to what he saw and what he saw but understood it was there.continue reading
Little known but well worth the visit, the Uncompahgre River is one of Colorado’s truly hidden treasures. The river flows through some of Colorado’s most rugged yet beautiful terrain, originating in the vicinity of Ouray and continuing northwards until it merges with the Gunnison River near Delta.
A number of government agencies have acted together to establish this magnificent resource into a reliable and rewarding source of fish for sportsmen, creating a superb fishery below the Ridgway Reservoir. Fishermen can expect to find lots of excellent trout with an abundance of insects as well.
Are you convinced? Here’s how to get there. Two highways run alongside this fine river, US 550 and 50. Getting access to the river is slightly more complex, but there are some exceptional places to visit in several parks and wildlife reserves. Check out the great fishing at the incomparable Uncompahgre River in Colorado.continue reading
