创建自定义的互动离散进化分布 [英] Creating a custom interated discrete evolutionary distribution

问题描述

我已经解决了这个问题几天了。我运行一个进化模型，使用物种之间的相互作用的分布。我在这里粘贴了函数。我需要使用模板：

I have been tackling this issue for days now. I am running an evolutionary model which uses a distribution for interactions between species. I pasted the function here. I need to use the template:

模板< class InputIt>

如果我直接在函数声明之前粘贴它，函数不会识别模板。如果我在main（）之前粘贴它，模板被识别，但我得到单个错误：

The function does not recognize the template if I paste it directly before the function declaration. If I paste it before main(), the template is recognized, but I get the single error:

错误2错误LNK1120：1未解决的外部

Error 2 error LNK1120: 1 unresolved externals

代码：

void evolution(TeamArray& teamData)
{

default_random_engine randomGenerator((unsigned int)time(NULL));
uniform_int_distribution<int> rand120(0, 120);

int* RandA;
int* RandB;

RandA = new int[rounds];
RandB = new int[rounds];
// Time Period 1

for (int i = 0; i < rounds / 10; ++i)
{
    RandA[i] = rand120(randomGenerator); // generates random numbers from 0 to 120 (121 elements)
}

for (int i = 0; i < rounds / 10; ++i)
{
    RandB[i] = rand120(randomGenerator); // generates random numbers from 0 to 120 (121 elements)
}

for (int i = 0; i < rounds / 10; i++)
{
    interact(teamData[RandA[i]], teamData[RandB[i]]);
}

delete[] RandA;
delete[] RandB;

    // Later time periods (ERA 2 through 10)

// The inside of this loop does the rest of the interactions 
for (int t = 1; t < 10; ++t) // looping through the ERA's
{
    // Intializing distribution 
    std::vector< int> weights(121);
    for (int i = 0; i < 121; i++)
    {
        weights[i] = (teamData[i]).S();
    }

    std::discrete_distribution<int&> dist(weights.begin(), weights.end());

    for (int i = t* (rounds / 10); i < (t+1) * (rounds / 10); ++i)
    {
        RandA[i] = dist(randomGenerator); 
    }

    for (int i = t* (rounds / 10); i < (t + 1) * (rounds / 10); ++i)
    {
        RandB[i] = dist(randomGenerator); 
    }

    for (int i = t* (rounds / 10); i < (t + 1) * (rounds / 10); ++i)
    {
        interact(teamData[RandA[i]], teamData[RandB[i]]);
    }

    delete[] RandA;
    delete[] RandB;
}

推荐答案

链接器，因为一个方法（在这种情况下是构造函数）被调用的签名与类中的任何特殊化都不匹配。

The error is reported by the linker because a method (in this case the constructor) is called with a signature that does not match any of the specialisations in the class.

std :: discrete_distribution 文档表明有4个专用构造函数可用，这些可能涵盖您需要的情况。

The std::discrete_distribution documentation indicates that there are 4 specialised constructors available and these may cover the case that you require.

您最接近您尝试调用的对象的引用需要 [InputInterator] [2] 不整数边界。

The one that you appear closest to the one you attempted to call requires [InputInterator][2] references, not integer bounds.

示例表示此构造函数在Microsoft平台上不可用，但提供了具有下限和上限的等效解决方案。

The example for Visual C++ indicates that this constructor is not available on the Microsoft platform but provides an equivalent solution with lower and upper bounds.
