JOpt.SDK is a tour optimization JAVA library that uses specialized genetic algorithms to calculate an optimized allocation of orders and stops to mobile resources. The algorithm not only provides tours at minimum costs but also considers an arbitrary set of constraints for each tour.
You may define your own constraints and optimization goals in order to customize JOpt.SDK to your specific planning needs or you decide to use one of our best practices addons in order to achieve a fast application of our optimization algorithms to selected industries.
JOpt.SDK can solve nearly any problem that can be classified by one of the following types:
TSP - Travelling Salesman Problem. JOpt.SDK finds the shortest or fastest path for your mobile resources
VRPTW - Vehicle routing problem with time windows - like TSP but for a set of vehicles. JOpt.SDK finds an optimal allocation of orders and stops within a vehicle fleet. It may also consider different constraints for vehicles, drivers and stops.
JOpt.SDK functionality can be accessed via JAVA API and thus fits seamlessly into any JAVA application. Software developers may integrate the JOpt.SDK component into their application in order to offer their customers a consistent solution including optimization of mobile workforce schedules. A seamless integration into your software allows the look and feel of one piece of software for your customer.
Enhancements:
- Support for Google Maps has been introduced.
- It is now possible to export optimization results to Google Maps.

Vendetta Online is a MMORPG (massively multiplayer online role-playing game) from Guild Software Inc. In this game, thousands of people can play together, at the same time, in a single, persistent universe. Players take the form of spaceship pilots within this universe, flying to and fro between space stations and other locations in the galaxy. All combat within the game is fully realtime, based entirely on "twitch" skill (no "virtual dice rolling"). Players may fight one another, fight NPCs, participate in groups, and even engage in large-scale Guild combat.

As pilots in the Vendetta universe, the progression of the players character is up to each individual. The starting Nation affiliation gives the player certain benefits and liabilities that fit the particular culture of that Nation, but this merely serves as a starting point for the character. If the user wishes to be a peaceful trader, military pilot, guard for hire, dastardly pirate, or whatever the player imagines, this is all up to the behaviour and play style of the user. There are both lawful and lawless places in the universe, and many different factions (including a pirate faction) with differing motives and shifting alignments. The universe is never a completely "safe" place, but lawful authorities do not take kindly to combat within their populated areas, making those places safer than most. More lawless regions may prove more dangerous, but potentially yield lucrative possibilities for those who align themselves with the darker underbelly of society. The life of a criminal is difficult, however, and pirates are not well-loved in most of the populated galaxy.

Character progression takes place in the form of a variety of skills and other attributes, any combination of which can potentially open up new gameplay content (missions, ships, equipment, trade items, etc). General activity related to a skill can increase it (trading can increase the Commerce skill, etc), but taking on missions will generally increase skills that much faster. Missions are offered by particular factions, with mission difficulty and availability increasing as the character becomes better known to the faction. Rising in the esteem of a given faction can itself yield better item prices, a wider item selection, and access to unusual "special" equipment available only to those who have proven themselves worthy. It is possible to win many types of accolades and commendations from particular factions, all of which can help demonstrate the characters accomplishments. These and other character stats may be viewed by other users in a Character Information panel.

The ships themselves are highly customizable, with various different designs and addon modules making possible a wide range of equipment loadouts. In addition, users may configure the color of their individual craft. Various types of ships are specifically suited to a particular task (such as combat or trading), while others prove more flexible, depending on how they are configured by the pilot.

Vendetta Online launched in North America in late 2004. Since then, continuous full-time development has pushed the game still further, towards the intended goal of "version 2.0" in 2007. Patches, upgrades and releases are usually seen on a weekly basis, the game ever-increasing in complexity as Guild Software gets closer to their next milestone. Since 2006, the userbase has also been helping out, creating new content via the Player Contribution Corps toolset, allowing the development of new missions and other features. The level of developer-userbase interaction is often considered one of the unique aspects of VO, with the core dev team posting and replying daily on the messageboard, and user-requested features often appearing in-game in a matter of days or weeks.

X-Plane project is the worlds most comprehensive, powerful flight simulator, and has the most realistic flight model available for personal computers.
Welcome to the world of props, jets, single- and multi-engine airplanes, as well as gliders, helicopters and VTOLs such as the V-22 Osprey and AV8-B Harrier.
X-Plane comes with subsonic and supersonic flight dynamics, sporting aircraft from the Bell 206 Jet-Ranger helicopter and Cessna 172 light plane to the supersonic Concorde and Mach-3 XB-70 Valkyrie. X-Plane comes with about 40 aircraft spanning the aviation industry (and history), and several hundred more are freely downloadable from the internet.
X-Plane scenery is world-wide, with scenery for the entire planet Earth AND MARS! (thanks to the Mars Orbiting Laser Altimeter, which mapped that planets elevation) You can land at any of over 18,000 airports, as well as test your mettle on aircraft carriers, helipads on building tops, frigates that pitch and roll in the waves, and oil rigs.
Weather is variable from clear skies and high visibility to thunderstorms with controllable wind, wind shear, turbulence, and microbursts! Rain, snow and clouds are available for an instrument flying challenge, and thermals are available for the gliders! Real weather conditions can be downloaded from the internet, allowing you to fly in the actual weather that currently exists!
X-Plane also has detailed failure-modeling, with 35 systems that can be failed manually or randomly, when you least expect it! You can fail instruments, engines, flight controls, and landing gear at any moment.
While X-Plane is the worlds most COMPREHENSIVE flight sim, your purchase also comes with Plane-Maker (to create your own airplanes) World-Maker (to create your own scenery), and Weather Briefer (to get a weather briefing before the flight if you use real weather conditions downloaded from the net).
X-Plane is also extremely customizable, allowing you to easily create textures, sounds, and instrument panels for your own airplanes that you design or the planes that come with the sim.
X-Planes accuracy (in flight model), scope (in aircraft and terrain coverage), versatility (in aircraft type and weather conditions), add-on programs (in aircraft and scenery editors), user-customizability, downloadable aircraft, and downloadable scenery makes it the ULTIMATE flight simulation experience for Macintosh AND Windows platforms.
X-Planes flight model can handle flying wings and fly-by-wire systems, as needed for a B-2 simulation.
How it Works:
1: Element Break-Down
Done only once during initialization, X-Plane breaks the wing(s), horizontal stabilizer, vertical stabilizer(s), and propeller(s) (if equipped) down into a finite number of elements. The number of elements is decided by the user in Plane-Maker. Ten elements per side per wing or stabilizer is the maximum, and studies have shown that this provides roll rates and accelerations that are very close to the values that would be found with a much larger number of elements.
2: Velocity Determination
This is done twice per cycle. The aircraft linear and angular velocities, along with the longitudinal, lateral, and vertical arms of each element are considered to find the velocity vector of each element. Downwash, propwash, and induced angle of attack from lift-augmentation devices are all considered when finding the velocity vector of each element.
Propwash is found by looking at the area of each propeller disk, and the thrust of each propeller. Using local air density, X-Plane determines the propwash required for momentum to be conserved.
Downwash is found by looking at the aspect ratio, taper ratio, and sweep of the wing, and the horizontal and vertical distance of the "washed surface" (normally the horizontal stabilizer) from the "washing surface" (normally the wing), and then going to an empirical look-up table to get the degrees of downwash generated per coefficient of lift.
3: Coefficient Determination
The airfoil data entered in Part-Maker is 2-dimensional, so X-Plane applies finite wing lift-slope reduction, finite-wing CLmax reduction, finite-wing induced drag, and finite-wing moment reduction appropriate to the aspect ratio, taper ratio, and sweep of the wing, horizontal stabilizer, vertical stabilizer, or propeller blade in question. Compressible flow effects are considered using Prandtl-Glauert, but transonic effects are not simulated other than an empirical mach-divergent drag increase. In supersonic flight, the airfoil is considered to be a diamond shape with the appropriate thickness ratio... pressures behind the shock waves are found on each of the plates in the diamond-shaped airfoil and summed to give the total pressures on the foil element.
4: Force Build-Up
Using the coefficients just determined in step 3, areas determined during step 1, and dynamic pressures (determined separately for each element based on aircraft speed, altitude, temperature, propwash and wing sweep), the forces are found and summed for the entire aircraft. Forces are then divided by the aircraft mass for linear accelerations, and moments of inertia for angular accelerations.
5: Get Back to Work
Go back to step 2 and do the whole thing over again at least 15 times per second. Arent computers great?
