public class IndividualCensus_ISARHP_ISARCEP_PC
- extends IndividualCensus_ISARHP_ISARCEP
Class for creating an individual census using sampling with replacement.
The Household Population (HP) is comprised from ISARDataRecords.
The Communal Establishment Population (CEP) is comprised from
ISARDataRecords.
The main method is for invoking on an individual PC and reads and writes
files from a single directory as specified in a configuration file along with
other parameters.
JVM Options:
-Xmx1200m
This ensures there is a minimum sufficient memory.
Additional requirements:
At least 15GB Disk for a full UK run.
This is with the default logging level, and default output formats. More disk
may be needed for finer logging levels depending on how much optimisation is
done.
Running this class requires a configuration file which can be specified via
the argument passed into the main method.
Either an existing solution is re-optimised or a new solution is generated
from scratch. Which is attempted depends on the configuration file.
The configuration file is a text file of which the first 10 lines are as
follows (quotation marks are not expected, they are added here for clarity
along with a brief explanation of each parameter):
line 1:
A workspace directory (e.g. "C:/Workspace/")
line 2:
A Local Authority District (LAD) Code (e.g. "00DA") or a region code
(e.g. "00D"), or "UK" in which case all LAD in the UK are processed.
line 3:
Output Level (e.g. "OA")
(Currently only OA for Output Areas is supported.)
Lines 4,5,6,7,8 and 9 are integer (int) Genetic Algorithm parameters:
Line 4:
_InitialPopulationSize the initial population size for an optimisation
(NB. This has to be 1 or more. The larger this is, the slower the first part
of the optimisation will be and the more resources will be required. A value
greater than 100 is not advised and a suggested value is 10.)
Line 5:
_NumberOfOptimisationIterations the number of optimisation iterations of an
optimisation
Line 6:
_MaxNumberOfSolutions the maximum number of solutions stored during an
optimisation.
(NB. This has to be 1 or more. The larger this is, the slower the
optimisation will be and the more resources will be required. A value
greater than 100 is not advised and a suggested value is 10.)
Line 7:
_ConvergenceThreshold the convergence threshold used during an optimisation.
If after this many iterations around the optimisation loop no better solution
is found, the program breaks out of the optimisation loop.
(NB. Sensibly this is greater than 1 and less than 100)
Line 8:
_MaxNumberOfMutationsPerChild the maximum number of mutations or changes per
child used during an optimisation
Line 9:
_MaxNumberOfMutationsPerParent the maximum number of mutations or changes per
parent used during an optimisation
Line 10:
_RandomSeed the seed for random number generation.
Line 11:
A String name to be used to specify the top level output directory.
Line 12:
The abstract file location of a file which is a result previously generated
output file in the form of a Serialized HashMap. It is expected this is
called population_HashMap.thisFile. If the file specified exists, it is
reloaded and used as an initial population for re-optimising.
The HP is created in 4 parts:
Household Reference Persons (HRP) for females,
HRP for males,
non-HRP for females,
non-HRP for males.
The CEP is created in 2 parts:
female,
males.
Each of these parts of the population are control constrained:
The HRP HP are constrained for each gender using age classes (0,20,30,60)
as in CAS003;
The non-HRP HP are constrained for each gender for household resident count
as in CAS001 (the total HRP HP for each gender is taken from the CAS001
count);
The CEP are constrained for each gender using age classes
(0,16,20,25,30,45,60,65,70,75,80,85,90).
By default all CEP have the expected ISARDataRecord.get_RELTOHR() type.
However, where necessary other such types are used.
