There are more than a google(10¹⁰⁰) alternative alignments in the 3D space of a 50km × 50km terrain when it is rasterized 20 meter to 20 meter. This is why we call it infinite space problem.

Until now all known solutions to corridor optimization have been based on two techniques: 

a) Emphasizing on analytical methods and 

b) Using two phase 2D methods to achieve a 3D alignment. In other words a horizontal corridor alignment, followed by a vertical optimization. 

Both techniques usually lead to missing significant results.

In some cases even a one meter shift in the corridor geometry might lead to millions of dollars of difference in construction costs due to amount of earthworks. There would be billions of better alignments that analytical methods might drop in comparison to Artificial Intelligence (AI) methods. The best solution is combining AI and analytical techniques.

After years of research and development, using extremely complex hybrid artificial intelligence technology, we have achieved a professional commercial version of the first full 3D corridor optimization expert system which combines AI and analytical methods. A solution with abilities superior to all optimization technologies in optimizing Road and Railway Corridors. 

An Army of Hundreds of Artificially Intelligent Robots That Know How to Design the Road and Railway Corridors and How to Find the Best One

To Run The Army of Robots, It Requires Mainframes or Grid Processing Environment With +100s CPU Cores.

We made simulated robots(BOTs) that have road design knowledge. They know how to move in the 3D Space of the terrain. They are thought how to plan cut and fill and plan bermings. They know when and how to choose the best type of bridges, culverts, retaining walls and tunnels. They even know how to configure the bridge to obtain lowest construction costs. They know unit costs of all main construction activities and structures. 

They work as teams.  Each team has a manager. Managers are guided by leaders and there is a prime leader which organizes their society.

They can change their behaviors based on situations. 

They can even give birth to new children and share their experience and jobs.

They move in the 3D space at the speed of 2.5 Machs. They can fly, run on the ground or dig into the ground.
