Varying a and b with c=0. Measuring timea

.

a=1a=2

.

b=112

.

b=234

.

.

If we want more c values, we can create more tables c=1

.

a=1a=2

.

b=1345

.

b=252

.

.

.

Another table c=2

.

a=1a=2

.

b=1345

.

b=252

.

.

.

.

Now consider measuring time, precision and recall varying a and b. Could also very c by adding more tables if we wanted to

.

a=1a=2

.

b=1time=11time=1

.

precision=0.5precision=0.5

.

recall=0.8recall=0.9

.

b=2time=11time=10

.

precision=0.51precision=0.5

.

recall=0.2recall=0.34

.

There probably exist other formats as well
