Things to try:
* in-lining the min and max expressions
* depending on the distribution of e, it may be faster to catch KeyErrors
def search1(m):
box = {}
for r,row in enumerate(m):
for c,e in enumerate(row):
try:
minc, minr, maxc, maxr = box[e]
box[e] = ( c < minc and c or minc,
r < minr and r or minr,
c > maxc and c or maxc,
r > maxr and r or maxr)
except KeyError:
box[e] = (c, r, c, r)
return box
