i've been rewriting old maze type thing did fun, though instead of being maze it's bit more abstract , shrinks down, can't if location in locations search. i've done basic nearest neighbour search , have tried optimise little, it's still slow, in every 10x more nodes, 1000x more calculations needed (167 billion @ 10,000 nodes, collision checking), don't think there's more can done this. here's code edited work itself, nodes class , iterate through each 1 , grab size/location attribute (changed node[0] , node[1] ). imagine node_list has thousands of values. dimensions = 3 dimensions_range = range(dimensions) def collision_check(node_list, location, size, bounds=none): #check new node within bounds (if set) if bounds: in dimensions_range: if not bounds[0][i] + size <= location[i] <= bounds[1][i] - size: return true #find if nodes overlapping node in node_list: size_total = siz...

in lecture, our professor said there reason behind using bne in branching rather using beq (and left figure out), example shown below. if ( == j ) i++ ; j-- ; which compiles down to bne $r1, $r2, l1 # branch if ! ( == j ) addi $r1, $r1, 1 # i++ l1: addi $r2, $r2, -1 # j-- also, in link , being implied convention in mips assembly implement conditional branching in negation manner. best bet was, keeping common case simple - , therefore fast-, because intuitively if checking equality expect more become equal, , therefore pc branch when not equal. think pushed hard make reasonable, still couldn't distinguish core difference between implementing in beq or in bne . appreciate if explains why. consider code if had used beq . might end this: beq $r1, $r2, l1 l2: addi $r2, $r2, -1 # j-- ... ... l1: addi $r1, $r1, 1 #i++ j l2 or this: beq $r1, $r2, l1 addi $r2, $r2, -1 # j-- j l2 l1: addi $r1, $r1, 1 #i++ addi $r2, $r2, -1 # j-- l2: ...
