I am a computational physicist working on societal applications of machine-learning techniques.

My research interests span multi-disciplinary fields involving Societal applications of Machine Learning, Decision-theoretic approach to automated Experimental Design, Bayesian statistical data analysis and signal processing.

Interested about the picture? Autonomous experimental design allows us to answer the question of where to take the measurements. More about it is here...

### Color-coded boarding scheme

The airlines board aircrafts in the ascending order of "Zones". Zone 1, 2 and 3 etc are called in order.
Everyone knows how chaotic and time consuming it is. Because the next person in line has to wait for people who are trying to stow their luggage. This creates a long line. So, It does make sense to fill the plane from the back and come progressively front-ward.   People with kids and needing assistance should be boarded first.

Recently there are various ideas being put forward to speed up the boarding airplanes. It seems that boarding from back of the plane and filling window-seat passengers are the best way [see 1 and 2]. I like the Wilma boarding scheme where the window seats are zone 1 and aisle seats are zone 3.

Having seen some of the schemes to speed up the boarding, I am inspired to propose a color-coded boarding scheme. My idea is closer to steffen's method (see figures).
In this scheme, instead of calling zones, the calling is dependent upon the color-codes say blue, green, purple, yellow etc. Blue and green color seats are  the window seats are are called first.  I realized that  in [2] it is similar to the wilma scheme.
If tickets are booked together, in the case of husband/wife/ friend scenario, they can be coded the same color.

The seats are filled from back to front in an alternate seats. As shown in the figure, 1, 2, 3 etc are blue and seats 19, 20, 21 etc are also blue. If 1 and 25 booked together, then they are grouped together as blue. The numbers 13, 14, 15 and 7, 8, 9 are green color. In this way, the passengers get enough space to move around to stow their luggage and should make boarding faster. The assignment of color code can be made while the boarding card is being printed. Alignment of passengers in the gate will make  the boarding smoother. Just an idea.
 Steffen method of seating order. See [2 ,3] for details. See text for details on how it might be possible to make it faster by color-coded boarding.

The final result might look like:
 Color coded boarded scheme. Blue and green are called  first by the  stewards  in a sequence. People who booked flights together get the same color code as in #5 or #18.
