Purchasing VPS Hosting

Normally used by companies with highly critical websites, or individuals who need greater power, security, and flexibility that typical web hosting packages may offer, VPS Hosting is rapidly gaining the interest of many. However, to ensure that the VPS Hosting is used in the most effective way to benefit the users is imperative. This is one of the best economical choices when it comes to hosting. It will give you the space that you need at half the price that a dedicated server would cost you.

Before you run out and purchase the first VPS Hosting package you find you will want to do the research needed to find a reliable company who can provide you with what you need at a price you can afford. Finding a service provider that offers hosting plans at an affordable rate, reliable customer support, reliable technical support, and the ability to add features as needed may be harder to find than you may think.

You will need to do a bit of browsing on the Internet in order to find the right company for you. You will want to compare prices for their VPS Hosting plans and any additional charges that may occur such as for the cPanel or installations. Some companies may charge a setup fee while others dont. Reading feedback from previous or current customers should always be a top priority. You dont want to go with a company that promises you the world to only find out later that in reality they are a horrible company. Being over charged for services is something else that you will want to avoid. If you find several companies that offer VPS Hosting with the price being approximately the same and then a different company has it charged much higher you know to avoid them all together. While some companies charge more for extra features there should be no reason for a large different between companies especially if many hold about the same rates.

If you find a company that you are interested in purchase a VPS Hosting plan for a single month to get a feel of what the company is like. After the first month if the company seems reliable and steady you may opt to purchase hosting for 3 6 months instead of just 30 days. Many service providers will give you a lower rate if you purchase the hosting for a longer period of time. Just make sure that they have live contact information available in case you need help or run into problems. A company that doesnt have instant chat or a phone number available should be avoided. You will have no way to contact them other than email which may take awhile to get a response.

Mixed Integer Programming

An Integer Programming problem is a mathematical optimization problem of which some or all of the variables are limited to be integral numbers. In a lot of settings the term Integer Programming refers to Integer Linear Programming also known as mixed integer programming. Integer programming is NP-hard. A special case is the 0-1 integer linear programming, in which the unknown values are binary. This is one of the 21 NP-complete problems of Karp.

In linear programming problems, all the variables are real numbers. In problems constrains and the function remain linear, but some or all of the variables are integers. So while linear programming has continuous variables, Integer programming has discrete (integer) variables and Binary Integer programming problems have binary variables. Mixed Integer programming problems have discrete and continuous variables, examples are numbers, 0/1 decisions. Non-linear conditions can be formulated as linear. (if-then conditions) Integer problems are much harder to solve than continuous problems. Discrete problems are often NP-complete. (no polygonal algorithm) The amount of solutions is limited in most cases, but limited can still be a large number.

Some examples of Integer Programming problems are: designing distribution networks, transportation planning, determination of series size in production, shift-schedules, frequency assignment in telecommunication, gate distribution in the aviation industry and determining the consistency of software releases.

To avoid any confusion, the simplex method, which can be used for normal linear programming problems, is not enough for solving integer linear programming problems. There are also no dual integer linear programming models and there are no sensitivity analyses that can be applied to integer linear programming models. In short; most of the common methods for solving linear programming problems, cannot be applied to integer programming.

A concrete example of an integer programming problem is the knapsack problem. In the knapsack problem there is a bag that can carry a maximum amount of kilograms. Then there are a few items that you want to fit in the bag. Every item has its own weight and its own value. The objective here is to a few items in the bag with the highest possible value possible. The decision problem form of the knapsack problem lies in the question: Can a value of at least X be achieved without exceeding the weight Y. The knapsack problem is a fairly simple and imaginative example of the knapsack problem. Most real life problems are far more complex.
