Description

The SSVQE algorithm (https://arxiv.org/abs/1810.09434) is a generalization of VQE to find low-lying eigenstates of a Hermitian operator. This specific implementation of SSVQE carries out one optimization procedure using weights.

Hi @JoelHBierman :)

Can you plain text your description please

[frankharkins]

Also, @JoelHBierman can you try to keep the description ~30 words? For example:

The SSVQE algorithm (https://arxiv.org/abs/1810.09434) is a generalization of VQE to find low-lying eigenstates of a Hermitian operator. This specific implementation of SSVQE carries out one optimization procedure using weights.

This description is just for the qiskit.org/ecosystem web page, where users will work out if the project is what they're looking for. They'll click through to your repo for more details on how it works.

I see, yes I'll shorten the description and move the rest to the README.

Standard tests

❌ The submission didn't pass the standard check.
Please follow minimal requirements for project or/and add ecosystem.json configuration in the root of the project.
Read more here https://github.com/qiskit-community/ecosystem/blob/main/docs/project_overview.md#adding-project-to-the-ecosystem.

Stable tests

⚠️ The submission didn't pass the stable check.
This means your project doesn't work with the latest version of Qiskit.
This is purely informational and doesn't affect your project joining the Ecosystem, but you may want to investigate the problem.

Development tests

⚠️ The submission didn't pass the development check.
This means your project might not work with the next version of Qiskit.
This is purely informational and doesn't affect your project joining Ecosystem.

Hi @JoelHBierman
Can you add the ecosystem.json file at the root of your repo with something like that :

{
    "dependencies_files": [
        "requirements.txt",
        "requirements-dev.txt"
    ],
    "extra_dependencies": [
        "pytest"
    ],
    "language": {
        "name": "python",
        "versions": ["3.9"]
    },
    "tests_command": [
        "pytest"
    ],
    "styles_check_command": [
        "pylint -rn ssvqe test"
    ],
    "coverages_check_command": [
        "coverage3 run -m pytest",
        "coverage3 report --fail-under=80"
    ]
}

[JoelHBierman]

Yes I'll work on that and add it shortly.
