Figure 1.
The graph shows the elapsed time required to calculate cqq using different approaches. inv M is the elapsed time to calculate the M matrix which is the core element to calculate cqq for a new individual. Update Reference is the elapse time to update M matrix, the cqq with and without phenotype shows the elapsed time to calculate cqq when there is or there is not phenotype for the individual, respectively. Their performances were very similar, and as such the lines overlap.
