fm.check_convexity_monotonicity_mob {Rfmtool}

Function for checking supermodularity of the set function v in Mobius representation

Description

Checks supermodularity of the set function v in Mobius representation using stan- dard check.

Usage

  fm.check_convexity_monotonicity_mob(v, len, env=NULL)

Arguments

v

matrix v stores fuzzy measurements consecutively in cardinal order v.

len

this is the length of array Mob (this array is usually smaller than 2^n), and is computed by fm.fm_arraysize_kadd(N, Kadd).

env

Environment variable obtained from fm.Init(n).

Value

output

The output is 1 or 0 to check for monotonicity.
