Configurable SIERRA Variables

Non-Batch Criteria variables which you can use to configure simulations. All batch criteria are variables, but not all variables are batch criteria.

• Experiment Setup

Experiment Setup

Configure Experiment time: length, controller cadence (Tick duration/timestep), and how many datapoints to capture per Experimental Run.

Cmdline Syntax

T{duration}[.K{ticks_per_sec}][.N{n_datapoints}

• duration - Duration of timesteps in seconds (not timesteps).

• ticks_per_sec - How many times each controller will be run per second.

• n_datapoints - # datapoints per Experimental Run to be captured; the capture interval (if configurable) should be adjusted in Project-derived class from the platform “Experiment setup class” (e.g., sierra.plugins.platform.argos.variables.exp_setup.ExpSetup for ARGoS).

Examples

• exp_setup.T1000: Experimental run will be 1,000 seconds long and have 1,000*5=5,000 timesteps, with default (50) # datapoints.

• exp_setup.T2000.N100: Experimental run will be 2,000 seconds long and have 2,000*5=10,000 timesteps, with 100 datapoints (1 every 20 seconds/100 timesteps).

• exp_setup.T10000.K10: Experimental run will be 10,000 seconds long, and have 10,000*10=100,000 timesteps with default (50) # datapoints.

• exp_setup.T10000.K10.N100: Experimental run will be 10,000 seconds long, and have 10,000*10=100,000 timesteps, with 100 datapoints (one every 100 seconds/1,000 timesteps).
