Consider the following sequential game. There are two players, Player 1 and Player 2,
who alternate turns, Each turn, each player can choose one of two actions: Across (A)
or Down (D). If either player chooses D on their turn, the game ends. Otherwise, it
becomes the other player's turn, who may again play either A or D. The game ends
after 100 turns for each player, if no player has played D previously.
Payoffs in the game are represented by the following game tree, where nodes denote
turns for each player, branches denote actions, and final payoffs are indicated at the
end of each branch (Player 1's payoff is the first number, Player 2's payoff is the
second):

Note that the sum of payoffs for each player is increasing by 1 each turn. However, a
player claims a slightly larger payoff if the game ends on their turn, rather than their
opponent's.
Assuming that both players strictly apply the principle of backward induction, what
payoffs will the…
Consider the following game (anachronistically) called the battle of the sexes. Two brothers, Shahid
and Jamil are spending their weekend in Philadelphia, but they have lost communication with each
other and Shahid is coming from New York where Jamil is coming from Washington DC. They are
trying to find out where they should meet when they arrive in Philadelphia: they want to meet up,
and both know that Shahid prefers meeting at Reading Terminal Market (he's a foodie!) and Jamil
prefers meeting at the Rocky Steps (he's a movie buff!). Not meeting up though would be the worst
outcome as it's the city of brotherly love. Suppose the game is represented by the following payoff
matrix with Jamil the row player:

- Correct answer will be upvoted else downvoted. Computer science. There are two potential results of a game: the game might bring about a tie, then, at that point, the two groups get 1 point; one group may dominate in a match, then, at that point, the triumphant group gets 3 focuses and the losing group gets 0 focuses. The score of a group is the number of focuses it acquired during all games that it played. You are keen on a theoretical circumstance when all groups get a similar score toward the finish of the title. A basic illustration of that circumstance is the point at which all games bring about ties, however you need to limit the number of ties too. Your assignment is to depict a circumstance (pick the aftereffect of each game) so that all groups get a similar score, and the number of ties is the base conceivable.

- In the game of 10-pin bowling the bowler has two attempts to knock down pins for every frame of 10-pins, and scores a point for each pin knocked down. If all the pins are knocked down with two attempts, the bowler gets a bonus - whatever score they obtain with their next bowl is doubled. If all the pins are knocked down on the 1st attempt, no 2nd attempt is allowed, and the bowler gets a bonus – whatever score they obtain on their next two bowls are doubled. A student attempts to capture this scoring system in VHDL code, a fragment of which is shown in Figure Q4. Q4 (a) Draw the state transition diagram described by the VHDL of Figure Q4.

- Casinos have devised different automated mechanical methods for shuffling the cards.One such method divides the deck into to seven piles by placing each card randomlyeither on the top or at the bottom of one pile (i.e. each card has 14 possible placesto choose from). After that, the piles are put together to form the shuffled deck.Is this a good method?

So when Kuldeep invites them to a party, both Raghu and Sayan decide to play a game. The game is simple, both Raghu and Sayan will eat the dishes served at the party till they are full, and the one who eats maximum number of distinct dishes is the winner. However, both of them can only eat a dishes if they can finish it completely i.e. if Raghu can eat only 50 kCal in a day and has already eaten dishes worth 40 kCal, then he can't eat a dish with calorie value greater than 10 kCal.Given that all the dishes served at the party are infinite in number, (Kuldeep doesn't want any of his friends to miss on any dish) represented by their calorie value(in kCal) and the amount of kCal Raghu and Sayan can eat in a day, your job is to find out who'll win, in case of a tie print “Tie” (quotes for clarity).
