 The first step of the simulation is importing a building plan. The UI requests the user to upload a file from which colors of patches in netlogo are imported. This step specifies the building layout. It determines wheater it is a wall, door, exit or walkable path.
-=== The setup ===
+=== The Setup ===
 After setup button is pressed the program runs series of calculations to find the path out. It finds all corners in the plan and detects rooms. When rooms are detected the program finds all exits and doors in those rooms. It asigns values to all patches in the way based on distance to exits or doors in the room that are closest to a exit. Agents than follow the path.

 Values asigned are stored until building plan changes. This allows the program to calculate the way only once when a plan gets imported. First setup will take a while because of calculations. Also when plan gets changed the program needs to recalculate of course.
-=== Let's Simulate ===
+=== The Simulation ===
 Because the blueprint can be different everytime the core of the problem was to detect rooms automaticly and simulate people acting inside of them. The walls and doors in a room are the only thing that people can actualy see, when they are inside of them. So people will escape through exits that are in the room, rather than go through one door eventhough there is a closer exit. Simply because they see the one in the room first. When people are stuck with clusters, the clusters move slowly, this means that more people causes the evacuation to slow down.

	Interesting numbers to look at were deviation of escape time which was highest at density of two hundred people. This could mean that two hundered people are certain break point where the evacuation starts to slow down. The same thing applies on blueprint #2 as well. However in the third blueprint deviations are high at the begining and than it falls down, which means that evacuation is fastest when there are less than hundered people inside.

 The simulation has been run multiple times with different number of people inside and different building plans. Average escape time, deviation and maximum escape time where extracted from messuared data. All details including graphs can be found in [[File:sim-results.xlsx]] where every blueprint has its own excel tab.

	So the simulation process is finding the balance between time that evacuation takes and allowed number of people for evacuation to be successful in certain time limit.

		+	The simulation ends when time limit is reached or when all people got out of the building so you can see the exact number of evacuated people or the exact time of getting all of them out.
