Objective-C实现马尔可夫链(Markov Chain)算法的示例代码如下:
#import@interface MarkovChain : NSObject- (instancetype)initWithTransitionMatrix:(NSDictionary *)matrix;- (NSDictionary *>*)computeProbabilityDistributionForState:(NSString*)state;- (NSDictionary *>*)computeProbabilityDistributionForInitialState;- (NSDictionary *>*)computeProbabilityDistributionOverTime;- (NSDictionary *>*)computeProbabilityDistributionForSteps:(NSInteger)steps;- (NSDictionary *>*)computeProbabilityDistributionForStep:(NSInteger)step;- (NSDictionary *>*)computeProbabilityDistributionForTimeSeries:(NSArray *)timeSeries;- (NSDictionary *>*)computeProbabilityDistributionForTimeSeriesWithStep:(NSInteger)step;- (NSDictionary *>*)computeProbabilityDistributionForTimeSeriesWithSteps:(NSInteger)steps;- (NSDictionary *>*)computeProbabilityDistributionForTimeSeriesWithStepsAndInitialState:(NSDictionary *)initialState;- (NSDictionary *>*)computeProbabilityDistributionForTimeSeriesWithStepsAndInitialStateWithStep:(NSInteger)step;- (NSDictionary *)simulateChainWithInitialState:(NSDictionary *)initialState;- (NSDictionary *)simulateChainWithInitialStateAndSteps:(NSDictionary *)initialState withSteps:(NSInteger)steps;- (NSDictionary *)simulateChainWithInitialStateAndStepsAndStep:(NSDictionary *)initialState withStep:(NSInteger)step;- (NSDictionary *)simulateChainWithInitialStateAndStepsAndTimeSeries:(NSDictionary *)initialState withTimeSeries:(NSArray *)timeSeries;- (NSDictionary *)simulateChainWithInitialStateAndStepsAndTimeSeriesWithStep:(NSDictionary *)initialState withStep:(NSInteger)step;- (NSDictionary *)simulateChainWithInitialStateAndStepsAndTimeSeriesWithSteps:(NSDictionary *)initialState withSteps:(NSInteger)steps;@end
在这个项目中,我们创建了一个名为MarkovChain的类,用于实现马尔可夫链算法。该类通过提供一个状态转移矩阵,可以计算出马尔可夫链模型下的概率分布。以下是类的主要方法:
initWithTransitionMatrix:
matrix作为参数。computeProbabilityDistributionForState:
computeProbabilityDistributionForInitialState:
computeProbabilityDistributionOverTime:
computeProbabilityDistributionForSteps:
computeProbabilityDistributionForStep:
computeProbabilityDistributionForTimeSeries:
computeProbabilityDistributionForTimeSeriesWithStep:
computeProbabilityDistributionForTimeSeriesWithSteps:
computeProbabilityDistributionForTimeSeriesWithStepsAndInitialState:
computeProbabilityDistributionForTimeSeriesWithStepsAndInitialStateWithStep:
simulateChainWithInitialState:
simulateChainWithInitialStateAndSteps:
simulateChainWithInitialStateAndStepsAndStep:
