NIELIT 2017 July Scientist B (CS) - Section B: 41
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 ... $t=80$, then the number of scalar multiplications needed is $248000$ $44000$ $19000$ $25000$

ISRO2020-79
Consider product of three matrices $M_1,M_2$ and $M_3$ having $w$ rows and $x$ columns, $x$ rows and $y$ columns, and $y$ rows and $z$ columns. Under what condition will it take less time to compute the product as $(M_1M_2)M_3$ than to compute $M_1(M_2M_3)$ ? Always take the same time $(1/x +1/z)<(1/w+1/y)$ $x>y$ $(w+x)>(y+z)$
