+## PERFORMANCE

 On a home computer with a Ryzen 5600X CPU, 64GB of 3200MHz DDR4 RAM (half of which was allocated to the Java Virtual Machine), and a PCIe 3.0 SSD, running Linux Mint 20.3 Edge (5.13 kernel), 
 the author ran a BiGpairSEQ simulation of a 96-well sample plate with 30,000 T cells/well comprising ~11,800 alphas and betas,
-taken from a sample of 4,000,000 distinct cells with an exponential frequency distribution.
+taken from a sample of 4,000,000 distinct cells with an exponential frequency distribution (lambda 0.6).

 With min/max occupancy threshold of 3 and 94 wells for matching, and no other pre-filtering, BiGpairSEQ identified 5,151 
 correct pairings and 18 incorrect pairings, for an accuracy of 99.652%.

-The simulation time was 14'22". If intermediate results were held in memory, this would be equivalent to the total elapsed time.
+The total simulation time was 14'22". If intermediate results were held in memory, this would be equivalent to the total elapsed time.

 Since this implementation of BiGpairSEQ writes intermediate results to disk (to improve the efficiency of *repeated* simulations
 with different filtering options), the actual elapsed time was greater. File I/O time was not measured, but took 
 slightly less time than the simulation itself. Real elapsed time from start to finish was under 30 minutes.

+As mentioned in the theory section, performance could be improved by implementing a more efficient algorithm for finding
+the maximum weighted matching.
+
+## BEHAVIOR WITH RANDOMIZED WELL POPULATIONS
+
+A series of BiGpairSEQ simulations were conducted using a cell sample file of 3.5 million unique T cells. From these cells,
+10 sample plate files were created. All of these sample plates had 96 wells, used an exponential distribution with a lambda of 0.6, and
+had a sequence dropout rate of 10%.
+
+The well populations of the plates were:
+* One sample plate with 1000 T cells/well
+* One sample plate with 2000 T cells/well
+* One sample plate with 3000 T cells/well
+* One sample plate with 4000 T cells/well
+* One sample plate with 5000 T cells/well
+* Five sample plates with each individual well's population randomized, from 1000 to 5000 T cells. (Average population ~3000 T cells/well.)
+
+All BiGpairSEQ simulations were run with a low overlap threshold of 3 and a high overlap threshold of 94.
+No optional filters were used, so pairing was attempted for all sequences with overlaps within the threshold values.
+
+Constant well population plate results:

+
+The average results for the randomized plates are closest to the constant plate with 3000 T cells/well.
+This and several other tests indicate that BiGpairSEQ treats a sample plate with a highly variable number of T cells/well
+roughly as though it had a constant well population equal to the plate's average well population.
