dSpeed= : Minimum decompression speed
cMem= : Maximum compression memory
lvl= : Searches for solutions which are strictly better than that compression lvl in ratio and cSpeed,
stc= : When invoked with lvl=, represents percentage slack in ratio/cSpeed allowed for a solution to be considered (Default 99%)
stc= : When invoked with lvl=, represents percentage slack in ratio/cSpeed allowed for a solution to be considered (Default 100%)
: In normal operation, represents percentage slack in choosing viable starting strategy selection in choosing the default parameters
(Lower value will begin with stronger strategies) (Default 90%)
preferSpeed= / preferRatio=
: Only affects lvl = invocations. Defines value placed on compression speed or ratio
when determining overall winner (default speed = 1, ratio = 5 for both, higher = more valued).
speedRatio= (accepts decimals)
: determines value of gains in speed vs gains in ratio
when determining overall winner (default 5 (1% ratio = 5% speed)).
tries= : Maximum number of random restarts on a single strategy before switching (Default 3)
Higher values will make optimizer run longer, more chances to find better solution.
memLog : Limits the log of the size of each memotable (1 per strategy). Setting memLog = 0 turns off memoization
-P# : generated sample compressibility
-t# : Caps runtime of operation in seconds (default : 99999 seconds (about 27 hours ))
-v : Prints Benchmarking output
