GATE CSE 2011 | Question: 38
Four Matrices $M_1, M_2, M_3$ and $M_4$ of dimensions $ p \times q, \:\:q \times r, \:\:r \times s$ and $s \times t$ respectively can be multiplied in several ways with different number of total scalar multiplications. For example when multiplied as ... $t=80$, then the minimum number of scalar multiplications needed is $248000$ $44000$ $19000$ $25000$
