The Pareto Alternate Termination pane is on the PEST Properties dialog box under Pareto.
The variables specified on the Pareto Alternate Termination pane are described in the PEST User Manual, Part I, Section 13.2.2. More extensive descriptions of these variables are in the PEST user manual. The variables specified on this pane appear in the Pareto section of the PEST control file.
ALT_TERM If ALT_TERM is activated, termination of PEST execution will occur if a user-nominated model output (i.e. an “observation” cited in the “observation data” section of the PEST control file) rises above, or falls below, a certain threshold, and stays above or below that threshold over a certain number of iterations.
OBS_TERM If ALT_TERM is activated, the monitored observation is OBS_TERM.
ABOVE_OR_BELOW If ALT_TERM is activated, ABOVE_OR_BELOW indicates whether PEST should terminate execution if OBS_TERM is above or below OBS_THRESH.
OBS_THRESH is the threshold for termination of PEST execution.
NUM_ITER_THRESH is the number of successive iterations for which this threshold must be either exceeded or undercut for termination of PEST execution.
