This problem exercises the basic concepts of game-playing using tic-tac-toe (noughts and crosses) as an example. we define x[n] as the number of rows, columns, or diagonals with exactly n x's and no o's. similarly, o[n] is the number of rows, columns, or diagonals with just n o's. the utility function thus assigns +1 to any position with x[3], = 1 and â1 to any position with o[3], - 1.all other terminal positions have utility 0. we will use a linear evaluation function defined as eval = 3*x[2] + x[1] - (3*o[2] + o[1])approximately how many possible games of tic-tac-toe are there? show the whole game tree starting from an empty board down to depth 2, (i. e., one x and one o on the board), taking symmetry into account. you should have 3 positions at level 1 and 12 at level 2.mark on your tree the evaluations of all the positions at level 2.mark on your tree the backed-up values for the positions at levels 1 and 0, using the minimax algorithm, and use them to choose the best starting move. circle the nodes at level 2 that would not be evaluated if alpha-beta pruning were applied, assuming the nodes are generated in the optimal order for alpha-beta pruning.

Arigid tank contains 10 kg of air at 137 kpa (abs) and 21°c. more air is added to the tank until the pressure and temperature rise to 242 kpa (abs) and 32°c, respectively. determine the amount of air added to the tank. [r-0.287 kj/kg k]

Afan that can provide air speeds up to 60 m/s is to be used in a low-speed wind tunnel with atmospheric air at 35 c. if one wishes to use the wind tunnel to study flat-plate boundary layer behavior up to reynolds numbes of re 10, what is the minimum plate length that should be used? at what distance from the leading edge would transition occur if the critical reynolds nurnber were rer,e = 5 Ă 105?

On solidification from a melt, the polymer polyethylene forms a semi-crystalline spherulite structure. (i) sketch an individual spherulite and label the amorphous and crystalline regions. (ii) draw a schematic to show the changes in specific volume with temperature during cooling from the melt, comparing it to the theoretical extremes of fully crystalline and fully amorphous (indicate tm and tg)
