A SUCCESSFUL BUSINESS STRATEGY

     


       In a town, there is a long street connecting bus station and train station.  A hotelier thought if he start a catering business at the middle of that street, he would be able to attract floating population from both the stations.  He started a hotel and flourished.  Some time later, another business men thought if he opens a Restaurant near bus-stand, he would get all the crowd from the bus-stand, but will loose all the people from railway station to the first established hotel.  So, starting his restaurant near the first hotel would be the optimum solution.  So the second business-man's thinking ran in the same lines as first business-man's.  Hence the second hotel came up near the first one.  Over the time, many business people thought in the same lines and many hotel came up near one another.  Slowly, the entire street was lined up with best hotels and the street was called 'Hotel street".  The town also became city.

      That is, why we see many hotels near one another in many towns.  This 'stabilization phenomenon' is called 'Nash equilibrium' in Economics.  It was invented by John Nash and he was given Nobel prize in 1994.  His life was made into film.  The bio-pic is called, 'the beautiful mind'. Business and games are similar.  This strategy is also applied in game theory.

 Definition:  " If each player has chosen a strategy and no player can benefit by changing strategies while the other players keep theirs unchanged, then the current set of strategy and their corresponding pay-offs constitutes a Nash Equilibrium" - from Wikipedia

 Examples
    1. Driving
     Say, two cars are moving in opposite directions on a road.  Suppose one driver is going in his left side and another driver attempts to move to his right side, than there will be a collision.  The best strategy is 'both drivers must keep to same side - left or right -decided by the countries' law and practice.  "Nash equilibrium' will force them to drive correctly and they will automatically do it.

 2. Medicine
     Medical shops, labs, hospitals doctors, whole sale companies all usually crowd around in one place.

 3. Advertisement and price
     Competitive companies spend almost equally on advertisements.  The price of their products also stabilizes in a particular price band.

 4. Law enforcement
     Say, traffic police have to control huge moving crowd.  If they give short, fast moving  paths to the crowd, every body will be in the right track without pandemonium.  That is, if authorities follow 'Nash strategy', it will be easier to implement law and order.

 Education:
     All students fall in the same course and same field in a particular year.  Because the students think that is the best option at that time.

 Wars:
     No country intend to engage in a war.  Because we know, there will be loss for everybody and that is not a good strategy.  But still, every country will go on spend for war arsenal.  The army and arsenal is always a country's deterrent.

LISSAJOUS FIGURES

  Definition:  "When a particle is subjected to two sine wave motion or two oscillatory motion at right angles, the particle describes lissajous figures".      We know sine wave motion and circular motion is basically same.  Hence we draw two circles A and B perpendicular to each other.  The circle B rotates twice faster than circle A.  That is, frequency of circle B is two times than that of A.        A particle at the intersection of two circles is subjected to two sine wave motion   A and B at 90 degree simultaneously.  The particle will describe figures depending on the frequency and phase of A and B .  In our case, the ratio of frequency is  1:2 and the two waves are in phase.        To draw lissajous figures :  A moving point in both the circles are chosen.   Here we should remember; during the time taken by the circle A to complete one rotation, circle B completes two.  Hence the points are marked on the circles according to their speed.  Then straight lines

THE PARABOLA

          A jet of water shooting from a hose pipe will follow a parabolic path.  What is the so special about parabola.    Y= x^2 Draw a graph for the above equation.  It will result in a parabola.  This parabola is also called unit parabola.  Any equation involving square will yield a parabola. Example:  Y = 2x^2 +3x+3 (also called quadratic equation)    X= 2 and -2, both  satisfies the equation 4 = X^2.  Parabolic equations always have two solutions.     Any motion taking place freely under gravity follows parabolic path. Examples:   An object dropped from a moving train,   A bomb dropped from flying plane,  A ball kicked upwards.      If a beam of light rays fall on the parabolic shaped mirror, they will be reflected and brought to focus on a point.  This fact is made use of in Dish Antenna, Telescope mirrors, etc.      Inverted parabola shape is used in the construction of buildings and bridges.  Because the shape is able to bear more weight.      A plane

CASINO'S GAME

           Let us find out how the casino survives with mathematics.      Say, your friend invite you for a game of dice.  You must bet (wager) 2 dollars.  If you roll 'six' you will get back 8 dollars.  The game will go on for 30 rounds.  All sounds good.      The probability of rolling 'six' is 1/6.  Since the game will be played for 30 times, the 'expected win' is 30*1/6 = 5.  That is, you are expected to win 5 rounds out of 30.  Hence your gain will be 5 * 8 =40 dollars.  ok.  This also implies that you will loose 25 rounds.  Hence your loss will be 25*2 =50 dollars.  Your net gain will be gain-less = 40-50 = -10 dollars. For 30 rounds, the loss is -10 dollars, Hence, for one round =-10/30 = -1/3 dollars.  There will be a loss of -1/3 or 0.33 dollars per round.  It is not a fair game.     Let us make a simple formula to calculate  'Pay out per round\. The probability for a win = p The pay-out in case of win = V No. of rounds = n The expect
