Function Documentation

checkKey()

bool checkKey ( std::unordered_map< int, int > &  map, int  key  )

inline

Check if a key is present in a unordered map

Parameters

map	unordered map of <int,int>

createVectorPerf()

std::vector<Perf> createVectorPerf ( std::string  id, Criteria &  criteria, std::vector< float > &  given_perf  )

inline

createVectorPerf creates a vector of performances given the id, criteria and values

Parameters

id	of the performance
criteria	criteria vector on which to associate the performances
given_perf	performances values in the same order as criteria vect

Returns

vect<Perf> performance vector

createVectorPerfWithNoPerf()

std::vector<Perf> createVectorPerfWithNoPerf ( std::string  id, Criteria &  criteria  )

inline

createVectorPerf creates a vector of performances with random values given the id and criteria

Parameters

id	of the performance
criteria	criteria vector on which to associate the performances

Returns

vect<Perf> performance vector

getCriterionIds()

std::vector<std::string> getCriterionIds ( std::vector< Perf >  vectPerf )

inline

getCriterionIds get vector of criterions ids of a performance vector

Parameters

vectPerf

performance vector

Returns

vector of criterion ids

getNameIds()

std::vector<std::string> getNameIds ( std::vector< Perf >  vectPerf )

inline

getNameIds get the names of each perfomance in a perfomance vector

Parameters

vectPerf

Performance vector from which we want the ids

Returns

vector of names (ids)

getPerfFromPerfVect()

std::vector<double> getPerfFromPerfVect ( std::vector< Perf > &  p )

inline

Extract only performance values from a vector of Perf objects

Parameters

p	vector of Perf objects

getPerfOfCrit()

Perf getPerfOfCrit ( std::vector< Perf > &  vectPerf, std::string  critId  )

inline

getPerfOfCrit get the performance for a given criterion in a performance vector.

Parameters

critId

criterion for which we want the perf

Returns

Perf for given critId

getRandomUniformFloat()

float getRandomUniformFloat ( unsigned long int  seed = time(NULL), float  min = 0, float  max = 1  )

inline

Random float number generator

Parameters

seed	to initiate the generator, default 0
min	min of generated number, default 0
max	max of generated number, default 1

Returns

random float number between min and max

getRandomUniformInt()

int getRandomUniformInt ( unsigned long int  seed = 0, int  min = 0, int  max = 100  )

inline

Random int number generator

Parameters

seed	to initiate the generator, default 0
min	min of generated number, default 0
max	max of generated number, default 100

Returns

random int number between min and max

operator<<()

template<typename T >

std::ostream& operator<<	(	std::ostream &	out,
		const std::vector< T > &	vec
	)

Overloading << operator for std::vector object

Parameters

out	ostream
vec	std::vector object

plotGlobalData()

void plotGlobalData ( AlternativesPerformance &  ap )

inline

Plots data distribution for a AlternativesPerformance object in order to see if populations are separable. This is useful for ProfileInitialization for example.

Parameters

ap	AlternativesPerformance object

plotProfile()

void plotProfile ( Profiles &  p )

inline

Plots a visualization of a Profiles object. Profile object must be set in "alt" mode in order to correctly plot.

Parameters

p	Profiles object

randomCategoriesLimits()

std::vector<float> randomCategoriesLimits ( int  nbCategories, unsigned long int  seed = time(NULL)  )

inline

randomCategoriesLimits creates random categories limits given the number of categories

Parameters

nbCategories	number of categories (and of limits) to create
seed	seed for random

Returns

vector of float representing categories limits

subVector()

template<typename T >

std::vector<T> subVector	(	std::vector< T > const &	v,
		int	m,
		int	n
	)

subVector get a sub-vector of a vector

Parameters

v	vector from which we want the sub vector
m	index of the beginning of subvector
n	index of the end of subvector

Returns

subvector
