is_contradicted_by: Find out which rules are conflicting

Description

Find out for a contradicting rule which rules are conflicting. This helps in determining and assessing conflicts in rule sets. Which of the rules should stay and which should go?

Usage

is_contradicted_by(x, rule_name, verbose = interactive())

Value

character with conflicting rules.

Arguments

x

validate::validator() object with rules.

rule_name

character with the names of the rules that are causing infeasibility.

verbose

if TRUE prints the

Examples

rules <- validator( x > 0)

is_infeasible(rules)

# infeasible system!
rules <- validator( rule1 = x > 0
                  , rule2 = x < 0
                  )

is_infeasible(rules)

detect_infeasible_rules(rules, verbose=TRUE)

# but we want to keep rule1, so specify that it has an Inf weight
detect_infeasible_rules(rules, weight=c(rule1=Inf), verbose=TRUE)

# detect and remove
make_feasible(rules, weight=c(rule1=Inf), verbose = TRUE)

# find out the conflict with rule2
is_contradicted_by(rules, "rule2", verbose = TRUE)
